Subject: [PATCH net-next] w5100: using eth_hw_addr_random() for random MAC and
 set device flag

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

Using eth_hw_addr_random() to generate a random Ethernet address
(MAC) to be used by a net device and set addr_assign_type.
Not need to duplicating its implementation.

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