Sorry for the long delay.
It took some time to complete the verification, as the environment I
used for testing is not something I can access freely. I apologize for
the inconvenience.
I have confirmed that applying the patch 1a0f25a52e08 to the Ubuntu
22.04 kernel (5.15) resolves the issue.
I’ve attached graphs showing the transmit/receive statistics before and
after applying the patch.
The data before May 30th is from before the patch was applied, and the
data after May 30th is from after the patch.
thank you! it's great that this resolves the issue
However, since kernel 5.15 still uses struct ice_ring instead of struct
ice_tx_ring, I was not able to apply the patch as-is.
I had to make two small modifications to replace struct ice_tx_ring with
struct ice_ring.
for me it was just one place to change (but there was also conflict in
need of manual resolution, so that makes it "two small modifications")
As shown above, the patch 1a0f25a52e08 appears to be effective on 5.15
as well, so I would greatly appreciate it if you could consider
backporting it.
I will send this as a patch to stable kernel 5.15, CC'ing you;
I think that Canonical will pick it up that way too
