bnx2x: Fix vlan credit issues for VFs
Starting with commit 2dc33bbc "bnx2x: Remove the sriov VFOP mechanism",
the bnx2x started enforcing vlan credits for all vlan configurations.
This exposed 2 issues:
- Vlan credits are not returned once a VF is removed; this causes a leak
of credits, and eventually will lead to VFs with no vlan credits.
- A vlan credit must be set aside for the Hypervisor to use, and should
not be visible to the VF.
Although linux VFs at the moment do not support vlan configuration [from the
VF side] which causes them to be resilient to this sort of issue, Windows VF
over linux hypervisors might fail to load as the vlan credits become depleted.
