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 packet=
s,
it does not handle the case where stats have been reset.
Something like:
...
eth_stats_get()
=3D stats->imissed was 5 packets
eth_stats_reset()
eth_stats_get()
=3D 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.
