Drivers are free to use a more permissive configuration than the requested

support HWTSTAMP_FILTER_V2_EVENT, then it should generally always upscale

/**
* 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.
*
* 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 "drop" 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 "carrier" 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 "carrier" 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 "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:
*
* - 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 "carrier" 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).

#!/bin/sh
# 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.
