Miller" <davem@...emloft.net>, Cong Wang <xiyou.wangcong@...il.com> Subject: [Patch net] net: allow setting mac address of loopback device We are trying to mirror the local traffic from lo to eth0, allowing setting mac address of lo to eth0 would make the ether addresses in these packets correct, so that we don't have to modify the ether header again. Since usually no one cares about its mac address (all-zero), it is safe to allow those who care to set its mac address.
