be2net: Fixed bugs related to PVID.
Fixed bug to make sure 'pvid' retrieval will work on big endian hosts. Fixed incorrect comparison between the Rx Completion's 16-bit VLAN TCI and the PVID. Now comparing only the relevant 12 bits corresponding to the VID. Renamed 'vid' field under Rx Completion to 'vlan_tag' to reflect accurate description.
