There was an issue with ethtool stats that
have not been cleared after tc had been deleted.
Fix this by resetting stats after deleting tc
by calling i40e_vsi_reset_stats() function after
distroying qdisc.

I think it would be good to elaborate on what the issue is,
perhaps with an example. I think this should be added to
