Hi Michael, how accurate is the stats refresh timer in bnxt?
This test is seeing ~10% of flakiness on bnxt, fewer packets
got counted than we sent. Could be something else but I suspect
the stats just didn't get refreshed. We give it 25% margin right
now.

Dimitiri, this skips for some drivers because they don't auto-enable
ntuple filters. Looks like other selftests have the same check and also
skip in netdev CI. So probably a separate / follow up task but I think
we need to add code to enable the filters if they were disabled.
