reviving rp-pppoe

[Matthias Andree]

Hi,

as a band-aid fix, because 5.1-CURRENT's ppp or netgraph or whatever is
spoiled and PPPoE no longer works (ppp can't open the device,
complaining about wrong netgraph node type, wants ether, gets socket),
I've reanimated the net/rp-pppoe port, shar attached.

I've stripped any conflicting stuff (i. e. pppoe-sniff), and I have only
tested using the "pppoe" program with "ppp", sample config: (Only the
set device line is different, it used to be "set device PPPoE:xl2".)

tdsl-rp:
  set device "!/usr/local/sbin/pppoe -Ixl2"
  set authname "000871111111111111111111#0001 at t-online.de"
  set authkey  "22222222"
  add default HISADDR
  set dial
  set login
  set timeout 0

Replace xl2 by the name of the interface that the ADSL modem is attached
to. I'm using "ppp -quiet -nat -ddial tdsl-rp" to start this.

Server mode is totally untested.

As I'm unaware of how a port from the Attic is revived, I'm just
attaching the shar of the port (no PR has been sent yet).
