Subject: ethernet: manually convert memcpy(dev_addr,..., sizeof(addr))
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c51e5062c18067ccdc85798c2051edfc37e2475d;p=uclinux-h8%2Flinux.git

ethernet: manually convert memcpy(dev_addr,..., sizeof(addr))

A handful of drivers use sizeof(addr) for the size of
the address, after manually confirming the size is
indeed 6 convert them to eth_hw_addr_set().
