I am not sure of the problem,
but I think you are using a different variation of the TEMAC than
I am.
My TEMAC is configured with a DMA_TYPE of 1 and a DRE TYPE of 0
I also thought the XPacketFifo code was for DMA TYPE 1 which I
beleive is the FIFO incarnation of the TEMAC.
This driver is supposed to work with your TEMAC - I think.
