| |
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
Using random_ether_addr() to generate a random Ethernet address (MAC) that is not multicast and has the local assigned bit set. Not need to duplicating its implementation.
spatch with a semantic match is used to found this problem. (http://coccinelle.lip6.fr/)
