This patch adds VLAN hardware support for Rhine chips.
The driver uses up to 3 additional bytes of buffer space when extracting
802.1Q headers; PKT_BUF_SZ should still be sufficient.
The initial code was provided by David Lv. I reworked it to use standard
kernel facilities. Coding style clean up mostly follows via-velocity.
Adapted to new interface for VLAN acceleration (per request of Jesse Gross).
