Subject: [net-next 02/12] ixgbe: Fix SR-IOV VLAN pool configuration

From: Alexander Duyck <aduyck@...antis.com>

The code for checking the PF bit in ixgbe_set_vf_vlan_msg was using the
wrong offset and as a result it was pulling the VLAN off of the PF even if
there were VFs numbered greater than 40 that still had the VLAN enabled.
