bgmac: increase rx ring size from 511 to 512
Limiting it to 511 looks like a failed attempt at leaving one descriptor empty to allow the hardware to stop processing a buffer that has not been prepared yet. However, this doesn't work because this affects the total ring size as well Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
