>Description:
When using D-Link quad network cards (DFE-580-TX) and VLAN, it is not possible to recieve full-size VLAN tagged frames. The MAC must be told to allow normal frames + VLAN tag to pass. Don't know if this is a problem with other cards using the same driver.

(PS. I know the constant + 4 sucks (see patch), but i couldn't find a constant)
>How-To-Repeat:
Setup a VLAN tagged interface and ping with big packets. The answer should not be recieved.
