My vote is to get additional information. Given the nature of
the workaround ("When we disable SR-IOV from bios , everything working
fine"), it's plausible that the underlying cause is something
platform-specific.

Interestingly, we've been chasing internally an issue with
bonding LACP mode on ice (E810-XXV, I think) when running on the Ubuntu
kernel. That manifests as occasional TX timeouts, and doesn't happen if
the Intel OOT driver is used, so I wonder if that bugzilla reporter is
also seeing TX timeouts that correlate with their ping failures.
