New Revision: 255021
URL: http://svnweb.freebsd.org/changeset/base/255021

Log:
  Prevent the full restart cycle every time arge_start() is called.  Only
  (re)start the interface when it is down.  This change fix a race with
  BOOTP where the response packet is lost because the interface is being
  reset by a netmask change right after send the packet.
