[PATCH] be2net: Fixed bugs related to PVID.

[PATCH] be2net: Fixed bugs related to PVID.

[Somnath Kotur]

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.
