become ippp (ISDN ppp) and irip (ISDN raw IP). The character device now
are called: /dev/isdn (isdnd <-> kernel communication), /dev/isdnctl (dialing
and other control), /dev/isdntrc* (tracing), /dev/isdnbchan* (raw B channel
access, i.e. for user land PPP) and /dev/isdntel* (telephone devices, i.e.
for answering machines).
ifconfig.pppoe* files.
Rename the source directory and files to match the primary purpose
of this utility - probably noone is using this for ISDN now anymore,
as isdnd has simpler ways to acomplish the same.
