Applied, but this driver is full of skeletons:

drivers/net/ethernet/marvell/mv643xx_eth.c: In function ‘rxq_refill’:
drivers/net/ethernet/marvell/mv643xx_eth.c:618:19: error: invalid operands to binary - (have ‘sk_buff_data_t’ and ‘unsigned char *’)

which is:

		size = skb->end - skb->data;

that is absolutely not a legal computation.

It happens to be in the only configuration for which this driver
can be enabled in Kconfig but that is no excuse for it :-)
