enic: fix an endian bug in enic_probe()
"num_vfs" is a u32 but we only use the high 16 bits and the low 16bits are left as zero. That isn't a problem for little endian systems but it will break on big endian ones. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
