bfin_gen_rand_mac() uses __DATE__ as the seed for random ethernet address. This makes the build non-deterministic. In the first place, it should not be implemented as a Bfin-specific function. Use eth_random_addr() instead. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Sonic Zhang <sonic.zhang@analog.com>
