+ * 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 may include packets discarded
+ * due to L2 address filtering but should not include packets dropped
+ * by the device due to buffer exhaustion 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 "frame" 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 "frame" 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 "frame" 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 "frame" 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.
+ *

+ * Part of aggregate "carrier" errors in `/proc/net/dev`.
+ *
+ * @tx_heartbeat_errors: Number of Heartbeat / SQE Test errors for
+ * old half-duplex Ethernet.
+ * Part of aggregate "carrier" errors in `/proc/net/dev`.
+ *
+ * For IEEE 802.3 devices possibly equivalent to:
+ *

+# This script demonstrates interaction of conntrack and vrf.
+# The vrf driver calls the netfilter hooks again, with oif/iif
+# pointing at the VRF device.
+#
+# For ingress, this means first iteration has iifname of lower/real
+# device. In this script, thats veth0.
+# Second iteration is iifname set to vrf device, tvrf in this script.
+#
+# For egress, this is reversed: first iteration has the vrf device,
+# second iteration is done with the lower/real/veth0 device.
+#
+# test_ct_zone_in demonstrates unexpected change of nftables
+# behavior # caused by commit 09e856d54bda5f28 "vrf: Reset skb conntrack
+# connection on VRF rcv"
+#
+# It was possible to assign conntrack zone to a packet (or mark it for
+# `notracking`) in the prerouting chain before conntrack, based on real iif.
+#
+# After the change, the zone assignment is lost and the zone is assigned based
+# on the VRF master interface (in case such a rule exists).
+# assignment is lost. Instead, assignment based on the `iif` matching
+# Thus it is impossible to distinguish packets based on the original
+# interface.
+#
+# test_masquerade_vrf and test_masquerade_veth0 demonstrate the problem
+# that was supposed to be fixed by the commit mentioned above to make sure
+# that any fix to test case 1 won't break masquerade again.
