Since Matthew Dodd fixed the existing vlan implementation (which, as I had
previously recognized, is far cleaner than mine) I have removed my
original patches. However, I still mantain a patch that removes the MTU
limitation for the fxp driver and allows it to receive full-length packets
(1500 bytes plus header). You can find it at:

Your patch does almost exactly the same as mine.
