This fixes a long standing bug in mxge(4) where "ifconfig mxge0 $IP" did not bring the interface into a RUNNING state, like it does on most (all?) other FreeBSD NIC drivers. Thanks to gnn for mentioning the bug, and yongari for pointing out that ether_ioctl() invokes ifp->if_init() in SIOCSIFADDR. MFC after: 7 days
