I am reasonably confident the patch is OK, but I cannot easily compile
it on my laptop (x86_64) :

CC drivers/net/ethernet/broadcom/bcm63xx_enet.o
drivers/net/ethernet/broadcom/bcm63xx_enet.c:34:30: fatal error:
bcm63xx_dev_enet.h: No such file or directory
#include <bcm63xx_dev_enet.h>

compilation terminated.
