Bug ID 1430
Summary af_xdp: reset stats has no effect on imissed
Product DPDK
Version 24.03
Hardware All
OS All
Status UNCONFIRMED
Severity minor
Priority Normal
Component ethdev
Assignee dev@dpdk.org
Reporter stephen@networkplumber.org
Target Milestone ---

Since the AF_XDP PMD queries the kernel to find the number of missed packets,
it does not handle the case where stats have been reset.

Something like:
        ...
        eth_stats_get()
              = stats->imissed was 5 packets
        eth_stats_reset()
        eth_stats_get()
              = stats->imissed will still be 5 packets

The driver needs to record the count in the reset handler and then
offset the read count on the next stats get.
