Unbreak non-H/W VLAN extraction case. Unlike other GigEs Yukon II always set VLAN bit when it detects VLAN tagged packet regardless of H/W VLAN processing configuration state. So it need to check IFCAP_VLAN_HWTAGGING bit to know whether driver is configured to take advantage of H/W VLAN processing. If H/W VLAN processing was disabled don't adjust received packet length such that subsequent validation logic works for software VLAN processing.
