Subject: [PATCH 35/35] ionic: restore netdev feature bits after reset
Git-commit: 155a1efc9b96a39857714aff49a11ebc93022c8c
Patch-mainline: v6.8-rc7
References: git-fixes
When rebuilding the lif after an FLR, be sure to restore the
current netdev features, not do the usual first time feature
init. This prevents losing user changes to things like TSO
or vlan tagging states.
Fixes: 45b84188a0a4 ("ionic: keep filters across FLR")
