[PATCH] airo: use is_zero_ether_addr() and is_broadcast_ether_addr()

[PATCH] airo: use is_zero_ether_addr() and is_broadcast_ether_addr()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

Using is_zero_ether_addr() and is_broadcast_ether_addr() instead of
directly use memcmp() to determine if the ethernet address is all zeros.

spatch with a semantic match is used to found this problem.
