Subject: ifconfig can't find cipcbN?

I've just noticed that in 2.6.13, though CIPE works just fine, the
basic ifconfig program cannot find a named cipcbN interface on its own.

I run a custom build of RH's .src.rpm, to turn on IKCONFIG, turn off
REGPARM, and fix a sched.c annoyance -- nothing net-specific in my
differences.  Is there anything already known as to why ifconfig
cannot find a named interface, but knows about it when showing all
interfaces?
