Nit: could you remove RxCfgFIFOShift and add something like 

#define RXCFG_FIFO_SHIFT	13
				/* No threshold before first PCI xfer. */
#define RXCFG_FIFO_THRESH	(7 << RXCFG_FIFO_SHIFT)
#define RXCFG_DMA_SHIFT		8
				/* Unlimited maximum PCI burst. */
#define	RXCFG_DMA_BURST		(7 << RXCFG_DMA_SHIFT)

(and move both RX128_INT_EN and RX_MULTI_EN near RxConfig in patch #1)
