Revert "networkd: netdev - set predictable mac address when creating netdev"
This reverts commit cdc85c875b842b9309f72caefc51c262f521cf92. There appears to be a kernel bug that (among other things) cause bridges not to get a bridge id set when supplying IFLA_ADDRESS when creating the netdev. Simply revert the whole thing until we sort this out in the kernel. See: http://www.spinics.net/lists/netdev/msg279807.html Reported-by: C. R. Oldham <cr@saltstack.com>
