Sorry for being obtuse, but just to clarify:

fxp just seems to have an "allow long frames" flag, rather than a "max frame size"
register in the hardware, so you never seem to have to tell the hardware the max
size of a frame it needs to accept. I assume you mean, that after setting if_hdrlen,
you still need to write to the PCI register, like this:
                CSR_WRITE_4(sc, BGE_RX_MTU,
                        ifp->if_mtu + ifp->if_hdrlen + ETHER_CRC_LEN);

I don't have a bge device, so I can't muck about with it to try.
