We don't list vlan support on the manpage for each driver. However there are other changes that should be mentioned. Rx checksum offload support was added, and the longword-alignment mentioned in BUGS is no longer required on the current chips, it seems simplest to remove BUGS completely but we could alternatively keep it and discuss which chips are affected. comments/oks?
