Thanks for this however it is not the problem I am experiencing at present,
my problem is with the TX and not the RX side of things, I have added debug
and the ibm_emac_core prints out that the packet has been transmitted,
however I see nothing at the other end when you transmit a packet of tx fifo
size bytes from the PPC 440 GX, packets of <tx fifo size or >tx fifo size
are transmitted fine from the PPC 440 GX, so long as you do not transmit a
packet of Tx fifo size.

Thanks
