     43  * struct rtnl_link_stats64 - The main device statistics structure.
     44  *
     45  * @rx_packets: Number of good packets received by the interface.
     46  *   For hardware interfaces counts all good packets received from the device
     47  *   by the host, including packets which host had to drop at various stages
     48  *   of processing (even in the driver).
     49  *
     50  * @tx_packets: Number of packets successfully transmitted.
     51  *   For hardware interfaces counts packets which host was able to successfully
     52  *   hand over to the device, which does not necessarily mean that packets
     53  *   had been successfully transmitted out of the device, only that device
     54  *   acknowledged it copied them out of host memory.
     55  *
     56  * @rx_bytes: Number of good received bytes, corresponding to @rx_packets.
     57  *
     58  *   For IEEE 802.3 devices should count the length of Ethernet Frames
     59  *   excluding the FCS.
     60  *
     61  * @tx_bytes: Number of good transmitted bytes, corresponding to @tx_packets.
     62  *
     63  *   For IEEE 802.3 devices should count the length of Ethernet Frames
     64  *   excluding the FCS.
     65  *
     66  * @rx_errors: Total number of bad packets received on this network device.
     67  *   This counter must include events counted by @rx_length_errors,
     68  *   @rx_crc_errors, @rx_frame_errors and other errors not otherwise
     69  *   counted.
     70  *
     71  * @tx_errors: Total number of transmit problems.
     72  *   This counter must include events counter by @tx_aborted_errors,
     73  *   @tx_carrier_errors, @tx_fifo_errors, @tx_heartbeat_errors,
     74  *   @tx_window_errors and other errors not otherwise counted.
     75  *
     76  * @rx_dropped: Number of packets received but not processed,
     77  *   e.g. due to lack of resources or unsupported protocol.
     78  *   For hardware interfaces this counter may include packets discarded
     79  *   due to L2 address filtering but should not include packets dropped
     80  *   by the device due to buffer exhaustion which are counted separately in
     81  *   @rx_missed_errors (since procfs folds those two counters together).
     82  *
     83  * @tx_dropped: Number of packets dropped on their way to transmission,
     84  *   e.g. due to lack of resources.
     85  *
     86  * @multicast: Multicast packets received.
     87  *   For hardware interfaces this statistic is commonly calculated
     88  *   at the device level (unlike @rx_packets) and therefore may include
     89  *   packets which did not reach the host.
     90  *
     91  *   For IEEE 802.3 devices this counter may be equivalent to:
     92  *
     93  *    - 30.3.1.1.21 aMulticastFramesReceivedOK
     94  *
     95  * @collisions: Number of collisions during packet transmissions.
     96  *
     97  * @rx_length_errors: Number of packets dropped due to invalid length.
     98  *   Part of aggregate "frame" errors in `/proc/net/dev`.
     99  *
    100  *   For IEEE 802.3 devices this counter should be equivalent to a sum
    101  *   of the following attributes:
    102  *
    103  *    - 30.3.1.1.23 aInRangeLengthErrors
    104  *    - 30.3.1.1.24 aOutOfRangeLengthField
    105  *    - 30.3.1.1.25 aFrameTooLongErrors
    106  *
    107  * @rx_over_errors: Receiver FIFO overflow event counter.
    108  *
    109  *   Historically the count of overflow events. Such events may be
    110  *   reported in the receive descriptors or via interrupts, and may
    111  *   not correspond one-to-one with dropped packets.
    112  *
    113  *   The recommended interpretation for high speed interfaces is -
    114  *   number of packets dropped because they did not fit into buffers
    115  *   provided by the host, e.g. packets larger than MTU or next buffer
    116  *   in the ring was not available for a scatter transfer.
    117  *
    118  *   Part of aggregate "frame" errors in `/proc/net/dev`.
    119  *
    120  *   This statistics was historically used interchangeably with
    121  *   @rx_fifo_errors.
    122  *
    123  *   This statistic corresponds to hardware events and is not commonly used
    124  *   on software devices.
    125  *
    126  * @rx_crc_errors: Number of packets received with a CRC error.
    127  *   Part of aggregate "frame" errors in `/proc/net/dev`.
    128  *
    129  *   For IEEE 802.3 devices this counter must be equivalent to:
    130  *
    131  *    - 30.3.1.1.6 aFrameCheckSequenceErrors
    132  *
    133  * @rx_frame_errors: Receiver frame alignment errors.
    134  *   Part of aggregate "frame" errors in `/proc/net/dev`.
    135  *
    136  *   For IEEE 802.3 devices this counter should be equivalent to:
    137  *
    138  *    - 30.3.1.1.7 aAlignmentErrors
    139  *
    140  * @rx_fifo_errors: Receiver FIFO error counter.
    141  *
    142  *   Historically the count of overflow events. Those events may be
    143  *   reported in the receive descriptors or via interrupts, and may
    144  *   not correspond one-to-one with dropped packets.
    145  *
    146  *   This statistics was used interchangeably with @rx_over_errors.
    147  *   Not recommended for use in drivers for high speed interfaces.
    148  *
    149  *   This statistic is used on software devices, e.g. to count software
    150  *   packet queue overflow (can) or sequencing errors (GRE).
    151  *
    152  * @rx_missed_errors: Count of packets missed by the host.
    153  *   Folded into the "drop" counter in `/proc/net/dev`.
    154  *
    155  *   Counts number of packets dropped by the device due to lack
    156  *   of buffer space. This usually indicates that the host interface
    157  *   is slower than the network interface, or host is not keeping up
    158  *   with the receive packet rate.
    159  *
    160  *   This statistic corresponds to hardware events and is not used
    161  *   on software devices.
    162  *
    163  * @tx_aborted_errors:
    164  *   Part of aggregate "carrier" errors in `/proc/net/dev`.
    165  *   For IEEE 802.3 devices capable of half-duplex operation this counter
    166  *   must be equivalent to:
    167  *
    168  *    - 30.3.1.1.11 aFramesAbortedDueToXSColls
    169  *
    170  *   High speed interfaces may use this counter as a general device
    171  *   discard counter.
    172  *
    173  * @tx_carrier_errors: Number of frame transmission errors due to loss
    174  *   of carrier during transmission.
    175  *   Part of aggregate "carrier" errors in `/proc/net/dev`.
    176  *
    177  *   For IEEE 802.3 devices this counter must be equivalent to:
    178  *
    179  *    - 30.3.1.1.13 aCarrierSenseErrors
    180  *
    181  * @tx_fifo_errors: Number of frame transmission errors due to device
    182  *   FIFO underrun / underflow. This condition occurs when the device
    183  *   begins transmission of a frame but is unable to deliver the
    184  *   entire frame to the transmitter in time for transmission.
    185  *   Part of aggregate "carrier" errors in `/proc/net/dev`.
    186  *
    187  * @tx_heartbeat_errors: Number of Heartbeat / SQE Test errors for
    188  *   old half-duplex Ethernet.
    189  *   Part of aggregate "carrier" errors in `/proc/net/dev`.
    190  *
    191  *   For IEEE 802.3 devices possibly equivalent to:
    192  *
    193  *    - 30.3.2.1.4 aSQETestErrors
    194  *
    195  * @tx_window_errors: Number of frame transmission errors due
    196  *   to late collisions (for Ethernet - after the first 64B of transmission).
    197  *   Part of aggregate "carrier" errors in `/proc/net/dev`.
    198  *
    199  *   For IEEE 802.3 devices this counter must be equivalent to:
    200  *
    201  *    - 30.3.1.1.10 aLateCollisions
    202  *
    203  * @rx_compressed: Number of correctly received compressed packets.
    204  *   This counters is only meaningful for interfaces which support
    205  *   packet compression (e.g. CSLIP, PPP).
    206  *
    207  * @tx_compressed: Number of transmitted compressed packets.
    208  *   This counters is only meaningful for interfaces which support
    209  *   packet compression (e.g. CSLIP, PPP).
    210  *
    211  * @rx_nohandler: Number of packets received on the interface
    212  *   but dropped by the networking stack because the device is
    213  *   not designated to receive packets (e.g. backup link in a bond).
    214  *
    215  * @rx_otherhost_dropped: Number of packets dropped due to mismatch
    216  *   in destination MAC address.

    413    IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
    414    more not changeable by user. They describe link media
    415    characteristics and set by device driver.
    416 
    417    Comments:
    418    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
    419    - If neither of these three flags are set;
    420      the interface is NBMA.
    421 
    422    - IFF_MULTICAST does not mean anything special:
    423    multicasts can be used on all not-NBMA links.
    424    IFF_MULTICAST means that this media uses special encapsulation
    425    for multicast frames. Apparently, all IFF_POINTOPOINT and
    426    IFF_BROADCAST devices are able to use multicasts too.

    466  * Please *note* that the timer values in the following section are expected
    467  * in clock_t format, which is seconds multiplied by USER_HZ (generally
    468  * defined as 100).
    469  *
    470  * @IFLA_BR_FORWARD_DELAY
    471  *   The bridge forwarding delay is the time spent in LISTENING state
    472  *   (before moving to LEARNING) and in LEARNING state (before moving
    473  *   to FORWARDING). Only relevant if STP is enabled.
    474  *
    475  *   The valid values are between (2 * USER_HZ) and (30 * USER_HZ).
    476  *   The default value is (15 * USER_HZ).
    477  *
    478  * @IFLA_BR_HELLO_TIME
    479  *   The time between hello packets sent by the bridge, when it is a root
    480  *   bridge or a designated bridge. Only relevant if STP is enabled.
    481  *
    482  *   The valid values are between (1 * USER_HZ) and (10 * USER_HZ).

    484  *
    485  * @IFLA_BR_MAX_AGE
    486  *   The hello packet timeout is the time until another bridge in the
    487  *   spanning tree is assumed to be dead, after reception of its last hello
    488  *   message. Only relevant if STP is enabled.
    489  *
    490  *   The valid values are between (6 * USER_HZ) and (40 * USER_HZ).
    491  *   The default value is (20 * USER_HZ).
    492  *
    493  * @IFLA_BR_AGEING_TIME
    494  *   Configure the bridge's FDB entries aging time. It is the time a MAC
    495  *   address will be kept in the FDB after a packet has been received from
    496  *   that address. After this time has passed, entries are cleaned up.
    497  *   Allow values outside the 802.1 standard specification for special cases:
    498  *
    499  *     * 0 - entry never ages (all permanent)
    500  *     * 1 - entry disappears (no persistence)
    501  *

    822  * @IFLA_BRPORT_STATE
    823  *   The operation state of the port. Here are the valid values.
    824  *
    825  *     * 0 - port is in STP *DISABLED* state. Make this port completely
    826  *       inactive for STP. This is also called BPDU filter and could be used
    827  *       to disable STP on an untrusted port, like a leaf virtual device.
    828  *       The traffic forwarding is also stopped on this port.
    829  *     * 1 - port is in STP *LISTENING* state. Only valid if STP is enabled
    830  *       on the bridge. In this state the port listens for STP BPDUs and
    831  *       drops all other traffic frames.
    832  *     * 2 - port is in STP *LEARNING* state. Only valid if STP is enabled on
    833  *       the bridge. In this state the port will accept traffic only for the
    834  *       purpose of updating MAC address tables.
    835  *     * 3 - port is in STP *FORWARDING* state. Port is fully active.
    836  *     * 4 - port is in STP *BLOCKING* state. Only valid if STP is enabled on
    837  *       the bridge. This state is used during the STP election process.
    838  *       In this state, port will only process STP BPDUs.
    839  *
    840  * @IFLA_BRPORT_PRIORITY
    841  *   The STP port priority. The valid values are between 0 and 255.
    842  *
    843  * @IFLA_BRPORT_COST
    844  *   The STP path cost of the port. The valid values are between 1 and 65535.
    845  *
    846  * @IFLA_BRPORT_MODE
    847  *   Set the bridge port mode. See *BRIDGE_MODE_HAIRPIN* for more details.
    848  *
    849  * @IFLA_BRPORT_GUARD
    850  *   Controls whether STP BPDUs will be processed by the bridge port. By
    851  *   default, the flag is turned off to allow BPDU processing. Turning this
    852  *   flag on will disable the bridge port if a STP BPDU packet is received.
    853  *
    854  *   If the bridge has Spanning Tree enabled, hostile devices on the network
    855  *   may send BPDU on a port and cause network failure. Setting *guard on*
    856  *   will detect and stop this by disabling the port. The port will be
    857  *   restarted if the link is brought down, or removed and reattached.
    858  *
    859  * @IFLA_BRPORT_PROTECT
    860  *   Controls whether a given port is allowed to become a root port or not.
    861  *   Only used when STP is enabled on the bridge. By default the flag is off.
    862  *
    863  *   This feature is also called root port guard. If BPDU is received from a
    864  *   leaf (edge) port, it should not be elected as root port. This could
    865  *   be used if using STP on a bridge and the downstream bridges are not fully
    866  *   trusted; this prevents a hostile guest from rerouting traffic.
    867  *
    868  * @IFLA_BRPORT_FAST_LEAVE
    869  *   This flag allows the bridge to immediately stop multicast traffic
    870  *   forwarding on a port that receives an IGMP Leave message. It is only used
    871  *   when IGMP snooping is enabled on the bridge. By default the flag is off.
    872  *
    873  * @IFLA_BRPORT_LEARNING
    874  *   Controls whether a given port will learn *source* MAC addresses from
    875  *   received traffic or not. Also controls whether dynamic FDB entries
    876  *   (which can also be added by software) will be refreshed by incoming
    877  *   traffic. By default this flag is on.
    878  *
    879  * @IFLA_BRPORT_UNICAST_FLOOD
    880  *   Controls whether unicast traffic for which there is no FDB entry will
    881  *   be flooded towards this port. By default this flag is on.
    882  *
    883  * @IFLA_BRPORT_PROXYARP
    884  *   Enable proxy ARP on this port.
    885  *
    886  * @IFLA_BRPORT_LEARNING_SYNC
    887  *   Controls whether a given port will sync MAC addresses learned on device
    888  *   port to bridge FDB.
    889  *
    890  * @IFLA_BRPORT_PROXYARP_WIFI
    891  *   Enable proxy ARP on this port which meets extended requirements by
    892  *   IEEE 802.11 and Hotspot 2.0 specifications.
    893  *
    894  * @IFLA_BRPORT_ROOT_ID

    915  *
    916  * @IFLA_BRPORT_FLUSH
    917  *   Flush bridge ports' fdb dynamic entries.
    918  *
    919  * @IFLA_BRPORT_MULTICAST_ROUTER
    920  *   Configure the port's multicast router presence. A port with
    921  *   a multicast router will receive all multicast traffic.
    922  *   The valid values are:
    923  *
    924  *     * 0 disable multicast routers on this port
    925  *     * 1 let the system detect the presence of routers (default)
    926  *     * 2 permanently enable multicast traffic forwarding on this port
    927  *     * 3 enable multicast routers temporarily on this port, not depending
    928  *         on incoming queries.
    929  *
    930  * @IFLA_BRPORT_PAD
    931  *
    932  * @IFLA_BRPORT_MCAST_FLOOD
    933  *   Controls whether a given port will flood multicast traffic for which
    934  *   there is no MDB entry. By default this flag is on.
    935  *
    936  * @IFLA_BRPORT_MCAST_TO_UCAST
    937  *   Controls whether a given port will replicate packets using unicast
    938  *   instead of multicast. By default this flag is off.
    939  *
    940  *   This is done by copying the packet per host and changing the multicast
    941  *   destination MAC to a unicast one accordingly.
    942  *
    943  *   *mcast_to_unicast* works on top of the multicast snooping feature of the
    944  *   bridge. Which means unicast copies are only delivered to hosts which
    945  *   are interested in unicast and signaled this via IGMP/MLD reports previously.
    946  *
    947  *   This feature is intended for interface types which have a more reliable
    948  *   and/or efficient way to deliver unicast packets than broadcast ones
    949  *   (e.g. WiFi).
    950  *
    951  *   However, it should only be enabled on interfaces where no IGMPv2/MLDv1
    952  *   report suppression takes place. IGMP/MLD report suppression issue is
    953  *   usually overcome by the network daemon (supplicant) enabling AP isolation
    954  *   and by that separating all STAs.
    955  *
    956  *   Delivery of STA-to-STA IP multicast is made possible again by enabling
    957  *   and utilizing the bridge hairpin mode, which considers the incoming port
    958  *   as a potential outgoing port, too (see *BRIDGE_MODE_HAIRPIN* option).
    959  *   Hairpin mode is performed after multicast snooping, therefore leading
    960  *   to only deliver reports to STAs running a multicast router.
    961  *
    962  * @IFLA_BRPORT_VLAN_TUNNEL
    963  *   Controls whether vlan to tunnel mapping is enabled on the port.
    964  *   By default this flag is off.
    965  *
    966  * @IFLA_BRPORT_BCAST_FLOOD
    967  *   Controls flooding of broadcast traffic on the given port. By default
    968  *   this flag is on.
    969  *
    970  * @IFLA_BRPORT_GROUP_FWD_MASK
    971  *   Set the group forward mask. This is a bitmask that is applied to
    972  *   decide whether to forward incoming frames destined to link-local
    973  *   addresses. The addresses of the form are 01:80:C2:00:00:0X (defaults
    974  *   to 0, which means the bridge does not forward any link-local frames
    975  *   coming on this port).
    976  *
    977  * @IFLA_BRPORT_NEIGH_SUPPRESS
    978  *   Controls whether neighbor discovery (arp and nd) proxy and suppression
    979  *   is enabled on the port. By default this flag is off.
    980  *
    981  * @IFLA_BRPORT_ISOLATED
    982  *   Controls whether a given port will be isolated, which means it will be
    983  *   able to communicate with non-isolated ports only. By default this
    984  *   flag is off.
    985  *
    986  * @IFLA_BRPORT_BACKUP_PORT
    987  *   Set a backup port. If the port loses carrier all traffic will be
    988  *   redirected to the configured backup port. Set the value to 0 to disable
    989  *   it.
    990  *
    991  * @IFLA_BRPORT_MRP_RING_OPEN
    992  *
    993  * @IFLA_BRPORT_MRP_IN_OPEN
    994  *
    995  * @IFLA_BRPORT_MCAST_EHT_HOSTS_LIMIT
    996  *   The number of per-port EHT hosts limit. The default value is 512.
    997  *   Setting to 0 is not allowed.
    998  *
    999  * @IFLA_BRPORT_MCAST_EHT_HOSTS_CNT
   1000  *   The current number of tracked hosts, read only.
   1001  *
   1002  * @IFLA_BRPORT_LOCKED
   1003  *   Controls whether a port will be locked, meaning that hosts behind the
   1004  *   port will not be able to communicate through the port unless an FDB
   1005  *   entry with the unit's MAC address is in the FDB. The common use case is
   1006  *   that hosts are allowed access through authentication with the IEEE 802.1X
   1007  *   protocol or based on whitelists. By default this flag is off.
   1008  *
   1009  *   Please note that secure 802.1X deployments should always use the
   1010  *   *BR_BOOLOPT_NO_LL_LEARN* flag, to not permit the bridge to populate its
   1011  *   FDB based on link-local (EAPOL) traffic received on the port.
   1012  *
   1013  * @IFLA_BRPORT_MAB
   1014  *   Controls whether a port will use MAC Authentication Bypass (MAB), a
   1015  *   technique through which select MAC addresses may be allowed on a locked
   1016  *   port, without using 802.1X authentication. Packets with an unknown source
   1017  *   MAC address generates a "locked" FDB entry on the incoming bridge port.
   1018  *   The common use case is for user space to react to these bridge FDB
   1019  *   notifications and optionally replace the locked FDB entry with a normal
   1020  *   one, allowing traffic to pass for whitelisted MAC addresses.
   1021  *
   1022  *   Setting this flag also requires *IFLA_BRPORT_LOCKED* and
   1023  *   *IFLA_BRPORT_LEARNING*. *IFLA_BRPORT_LOCKED* ensures that unauthorized
   1024  *   data packets are dropped, and *IFLA_BRPORT_LEARNING* allows the dynamic
   1025  *   FDB entries installed by user space (as replacements for the locked FDB
   1026  *   entries) to be refreshed and/or aged out.
   1027  *
   1028  * @IFLA_BRPORT_MCAST_N_GROUPS
   1029  *
   1030  * @IFLA_BRPORT_MCAST_MAX_GROUPS
   1031  *   Sets the maximum number of MDB entries that can be registered for a
   1032  *   given port. Attempts to register more MDB entries at the port than this
   1033  *   limit allows will be rejected, whether they are done through netlink
   1034  *   (e.g. the bridge tool), or IGMP or MLD membership reports. Setting a
   1035  *   limit of 0 disables the limit. The default value is 0.
   1036  *
   1037  * @IFLA_BRPORT_NEIGH_VLAN_SUPPRESS
   1038  *   Controls whether neighbor discovery (arp and nd) proxy and suppression is
   1039  *   enabled for a given port. By default this flag is off.
   1040  *
   1041  *   Note that this option only takes effect when *IFLA_BRPORT_NEIGH_SUPPRESS*
   1042  *   is enabled for a given port.
   1043  *
   1044  * @IFLA_BRPORT_BACKUP_NHID
   1045  *   The FDB nexthop object ID to attach to packets being redirected to a
   1046  *   backup port that has VLAN tunnel mapping enabled (via the
   1047  *   *IFLA_BRPORT_VLAN_TUNNEL* option). Setting a value of 0 (default) has
   1048  *   the effect of not attaching any ID.
