/*
plipconfig.c: plip-ifconfig program for the Linux PLIP device driver
Copyright (c) 1994 John Paul Morrison (VE7JPM).
version 0.2
Changed by Alan Cox, to reflect the way SIOCDEVPRIVATE is meant to work
and for the extra parameter added by Niibe.
plipconfig is a quick hack to set PLIP parameters by using driver
ioctls. plipconfig will no doubt be revised many times as the Linux
PLIP driver and Linux 1.1 mutates.
