[netdevice] Pass both link-layer addresses in net_tx() and net_rx()

Browse Source 
FCoE requires the use of fabric-provided MAC addresses, which breaks
the assumption that the net device's MAC address is implicitly the
source address for net_tx() and the (unicast) destination address for
net_rx().
