We hoped that with dual-channel NIC we could be able to just move
the received frame from one port for TX on another port, to overcome
the 32-bit PCI bus speed limitation, to get better thoroughput with
GigE.  Bill Paul already explained in private that they are actually
two distinct SRAMs, and the operation we needed is not supported
(without PCI involved).

Thanks to everyone who replied!
