ifconfig — configure network interfaces

       Configure network interfaces.

       Mandatory or optional arguments to long options are also mandatory  or  optional  for  any  corresponding
       short options.

       Known  flags  are:  allmulti,  arp, automedia, broadcast, debug, dynamic, master, multicast, pointopoint,
       portsel, promisc, slave, trailers, up.  Prepending no to any of these flags will negate their effect.
