     ifconfig — configure network interfaces

SYNOPSIS

     ifconfig [option ...] name [addr] [broadcast brdaddr] [{ pointopoint | dstaddr } dstaddr]
              [netmask mask] [{ ether | hwaddr | lladdr } macaddr] [metric n] [mtu n]
              [txqueuelen n] [up | down] [flags]

DESCRIPTION

     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.
