The e100 driver in the kernel does vlan hwaccel. You could look at that. Alternatively, as long as you can send and receive 1522 byte frames you could use the normal (non h/w acceleration) mode. This is a very straightforward mod to any ethernet driver - see for example the patches on the linux 802.1q vlan website. Regards, Alex
