qlcnic: VF FLR implementation.
o FLR from Hypervisor - When hypervisor issues a VF FLR request,
adapter notifies the parent PF driver of the FLR request for PF
driver to perform any cleanup on behalf of that VF.
o FLR from VF Driver - VF driver may initiate a VF FLR request,
if VF state needs to be cleaned up before a re-initialization.
VF re-initialization during kdump is an example.
o PF driver cleans up all resources allocated on behalf of a VF,
on VF FLR notifications from the adapter or from the VF driver.
