[PATCH net] qed: FLR of active VFs might lead to FW assert

[Yuval Mintz]

Driver never bothered marking the VF's vport with the VF's sw_fid.
As a result, FLR flows are not going to clean those vports.

If the vport was active when FLRed, re-activating it would lead
to a FW assertion.

Fixes: dacd88d6f6851 ("qed: IOV l2 functionality")

Hi Dave,

Please consider applying this to 'net'.

Thanks,
Yuval
