I tried out all 3 configurations and it didn't seem to help.  We are using
the Marvell Phy on our prototype.  The weird thing is it seems to work
perfectly every once in awhile, but not very often.  I seem to have tracked
the problem to the FifoRecvHandler tasklet function in xlltemac_main.c it
gets stuck in this while loop:
while (XLlFifo_RxOccupancy(&lp->Fifo) != 0) {
the XLlFifo_RxOccupancy always reads the same value.
Any ideas?

Thanks
Kevin
