Trying to write a bootp client for Ultrix

[Lance C Norskog]

You have a logical conundrum here.  You are trying to figure out how
to "turn on" IP, but you are trying to use IP to figure this out.

You have to send and receive your own raw Ethernet packets.  Ultrix
may have some technique for doing this.  System V has it's own scheme
where the Ethernet devices have their own /dev entries (jeeez wotta concept)
which you open and "bind" to a protocol number.

good luck.
