Sounds good! I think we should take that direction. This would also be totally
independent of the underlaying ppp implentation. That means, if it works,
it can be re-used for the other ppp implementations as well (syncppp, generic).
Then, pppd support can migrate to using packet sockets instead of /dev/*ppp*
and all ppp stacks can migrate smoothly. On the long run, I think we should
support the generic ppp by isdn, but with the current call / demand
dialing this won't be easy befor a major rewrite of the isdn link level
has been done. (This rewrite would of corse use the generic ppp).
