[ upstream commit 1bcb5ecb179cbca81ff3fe15432326c1c3ca9e9b ]

drivers/net/nfp/nfp_net.c:669:2: error:
‘memcpy’ forming offset [5, 6] is out of the bounds [0, 4]
of object ‘tmp’ with type ‘uint32_t’ {aka ‘unsigned int’}
[-Werror=array-bounds]
memcpy(&hw->mac_addr[0], &tmp, sizeof(struct ether_addr));

Fixes: e6decee38209 ("net/nfp: use random MAC address if not configured")
