    bnx2x: Fix vlan credit issues for VFs · 1a3d9424

    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.
