RE: [PATCH net 5/7] bnx2x: do not rollback VF MAC/VLAN filters we did not configure

On failure to configure a VF MAC/VLAN filter we should not attempt to
rollback filters that we failed to configure with -EEXIST.

Is this theoretical or did you actually manage to hit it?
If so, did it involve non-linux VFs?

Asking as linux VFs don't actually send multiple vlan/umac configurations
Via same request, and with a single filter per-message you're not expected
to ever do rollback.
