Kernel pppoe client on SGI

[Johan Hattne <hattne_(_at_)_EMBL-Hamburg_(_dot_)_DE>]

I realise my setup may be a bit uncommon, and maybe I shouldn't expect
things to work at this stage.  Nevertheless, I have problems getting pppoe
to work on an SGI snapshot from Feb 9 2005.  It seems to disconnect right
after authenticating:

  ...
  Feb  9 21:12:42 bagel /bsd: pppoe0: phase establish
  Feb  9 21:12:46 bagel /bsd: pppoe0: phase authenticate
  Feb  9 21:12:46 bagel /bsd: pppoe0: phase network
  Feb  9 21:12:52 bagel /bsd: pppoe0: phase terminate
  Feb  9 21:13:02 bagel /bsd: pppoe0: phase dead
  Feb  9 21:13:02 bagel /bsd: pppoe0: phase establish
  Feb  9 21:13:06 bagel /bsd: pppoe0: phase authenticate
  Feb  9 21:13:06 bagel /bsd: pppoe0: phase network
  Feb  9 21:13:12 bagel /bsd: pppoe0: phase terminate
  Feb  9 21:13:22 bagel /bsd: pppoe0: phase dead
  ...

And so on until pppoe0 is taken down.  Enabeling debugging output on the
interface, I have instead:

  ...

Which again, repeats.  I don't know enough to make sense out of this, but
I get the impression things break down after ipcp_open().  Anybody seen
this before or can hint at how to proceed?
