New Revision: 220385
URL: http://svn.freebsd.org/changeset/base/220385

Log:
  Implement mxge_init()
  
  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
