MFC r318160, 318176: Persistently store NIC's hardware MAC address, and add
a way to retrive it The MAC address reported by `ifconfig ${nic} ether' does not always match the address in the hardware, as reported by the driver during attach. In particular, NICs which are components of a lagg(4) interface all report the same MAC. When attaching, the NIC driver passes the MAC address it read from the hardware as an argument to ether_ifattach(). Keep a second copy of it, and create ioctl(SIOCGHWADDR) to return it. Teach `ifconfig' to report it along with the active MAC address. PR: 194386
