/**
 * struct rtnl_link_stats64 - The main device statistics structure.
 *
 * @rx_packets: Number of good packets received by the interface.
 *   For hardware interfaces counts all good packets received from the device
 *   by the host, including packets which host had to drop at various stages
 *   of processing (even in the driver).
 *
 * @tx_packets: Number of packets successfully transmitted.
 *   For hardware interfaces counts packets which host was able to successfully
 *   hand over to the device, which does not necessarily mean that packets
 *   had been successfully transmitted out of the device, only that device
 *   acknowledged it copied them out of host memory.
 *
 * @rx_bytes: Number of good received bytes, corresponding to @rx_packets.
 *
 *   For IEEE 802.3 devices should count the length of Ethernet Frames
 *   excluding the FCS.
 *
 * @tx_bytes: Number of good transmitted bytes, corresponding to @tx_packets.
 *
 *   For IEEE 802.3 devices should count the length of Ethernet Frames
 *   excluding the FCS.
 *
 * @rx_errors: Total number of bad packets received on this network device.
 *   This counter must include events counted by @rx_length_errors,
 *   @rx_crc_errors, @rx_frame_errors and other errors not otherwise
 *   counted.
 *
 * @tx_errors: Total number of transmit problems.
 *   This counter must include events counter by @tx_aborted_errors,
 *   @tx_carrier_errors, @tx_fifo_errors, @tx_heartbeat_errors,
 *   @tx_window_errors and other errors not otherwise counted.
 *
 * @rx_dropped: Number of packets received but not processed,
 *   e.g. due to lack of resources or unsupported protocol.
 *   For hardware interfaces this counter should not include packets
 *   dropped by the device which are counted separately in
 *   @rx_missed_errors (since procfs folds those two counters together).
 *
 * @tx_dropped: Number of packets dropped on their way to transmission,
 *   e.g. due to lack of resources.
 *
 * @multicast: Multicast packets received.
 *   For hardware interfaces this statistic is commonly calculated
 *   at the device level (unlike @rx_packets) and therefore may include
 *   packets which did not reach the host.
 *
 *   For IEEE 802.3 devices this counter may be equivalent to:
 *
 *    - 30.3.1.1.21 aMulticastFramesReceivedOK
 *
 * @collisions: Number of collisions during packet transmissions.
 *
 * @rx_length_errors: Number of packets dropped due to invalid length.
 *   Part of aggregate &quot;frame&quot; errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter should be equivalent to a sum
 *   of the following attributes:
 *
 *    - 30.3.1.1.23 aInRangeLengthErrors
 *    - 30.3.1.1.24 aOutOfRangeLengthField
 *    - 30.3.1.1.25 aFrameTooLongErrors
 *
 * @rx_over_errors: Receiver FIFO overflow event counter.
 *
 *   Historically the count of overflow events. Such events may be
 *   reported in the receive descriptors or via interrupts, and may
 *   not correspond one-to-one with dropped packets.
 *
 *   The recommended interpretation for high speed interfaces is -
 *   number of packets dropped because they did not fit into buffers
 *   provided by the host, e.g. packets larger than MTU or next buffer
 *   in the ring was not available for a scatter transfer.
 *
 *   Part of aggregate &quot;frame&quot; errors in `/proc/net/dev`.
 *
 *   This statistics was historically used interchangeably with
 *   @rx_fifo_errors.
 *
 *   This statistic corresponds to hardware events and is not commonly used
 *   on software devices.
 *
 * @rx_crc_errors: Number of packets received with a CRC error.
 *   Part of aggregate &quot;frame&quot; errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter must be equivalent to:
 *
 *    - 30.3.1.1.6 aFrameCheckSequenceErrors
 *
 * @rx_frame_errors: Receiver frame alignment errors.
 *   Part of aggregate &quot;frame&quot; errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter should be equivalent to:
 *
 *    - 30.3.1.1.7 aAlignmentErrors
 *
 * @rx_fifo_errors: Receiver FIFO error counter.
 *
 *   Historically the count of overflow events. Those events may be
 *   reported in the receive descriptors or via interrupts, and may
 *   not correspond one-to-one with dropped packets.
 *
 *   This statistics was used interchangeably with @rx_over_errors.
 *   Not recommended for use in drivers for high speed interfaces.
 *
 *   This statistic is used on software devices, e.g. to count software
 *   packet queue overflow (can) or sequencing errors (GRE).
 *
 * @rx_missed_errors: Count of packets missed by the host.
 *   Folded into the &quot;drop&quot; counter in `/proc/net/dev`.
 *
 *   Counts number of packets dropped by the device due to lack
 *   of buffer space. This usually indicates that the host interface
 *   is slower than the network interface, or host is not keeping up
 *   with the receive packet rate.
 *
 *   This statistic corresponds to hardware events and is not used
 *   on software devices.
 *
 * @tx_aborted_errors:
 *   Part of aggregate &quot;carrier&quot; errors in `/proc/net/dev`.
 *   For IEEE 802.3 devices capable of half-duplex operation this counter
 *   must be equivalent to:
 *
 *    - 30.3.1.1.11 aFramesAbortedDueToXSColls
 *
 *   High speed interfaces may use this counter as a general device
 *   discard counter.
 *
 * @tx_carrier_errors: Number of frame transmission errors due to loss
 *   of carrier during transmission.
 *   Part of aggregate &quot;carrier&quot; errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter must be equivalent to:
 *
 *    - 30.3.1.1.13 aCarrierSenseErrors
 *
 * @tx_fifo_errors: Number of frame transmission errors due to device
 *   FIFO underrun / underflow. This condition occurs when the device
 *   begins transmission of a frame but is unable to deliver the
 *   entire frame to the transmitter in time for transmission.
 *   Part of aggregate &quot;carrier&quot; errors in `/proc/net/dev`.
 *
 * @tx_heartbeat_errors: Number of Heartbeat / SQE Test errors for
 *   old half-duplex Ethernet.
 *   Part of aggregate &quot;carrier&quot; errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices possibly equivalent to:
 *
 *    - 30.3.2.1.4 aSQETestErrors
 *
 * @tx_window_errors: Number of frame transmission errors due
 *   to late collisions (for Ethernet - after the first 64B of transmission).
 *   Part of aggregate &quot;carrier&quot; errors in `/proc/net/dev`.
 *
 *   For IEEE 802.3 devices this counter must be equivalent to:
 *
 *    - 30.3.1.1.10 aLateCollisions
 *
 * @rx_compressed: Number of correctly received compressed packets.
 *   This counters is only meaningful for interfaces which support
 *   packet compression (e.g. CSLIP, PPP).
 *
 * @tx_compressed: Number of transmitted compressed packets.
 *   This counters is only meaningful for interfaces which support
 *   packet compression (e.g. CSLIP, PPP).
 *
 * @rx_nohandler: Number of packets received on the interface
 *   but dropped by the networking stack because the device is
 *   not designated to receive packets (e.g. backup link in a bond).

   IFF_* flags.

   The only change is:
   IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
   more not changeable by user. They describe link media
   characteristics and set by device driver.

   Comments:
   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
   - If neither of these three flags are set;
     the interface is NBMA.

   - IFF_MULTICAST does not mean anything special:
   multicasts can be used on all not-NBMA links.
   IFF_MULTICAST means that this media uses special encapsulation
   for multicast frames. Apparently, all IFF_POINTOPOINT and
   IFF_BROADCAST devices are able to use multicasts too.
