Re: HEAD UP: non-MPSAFE network drivers to be disabled

However the line discipline was a very convenient place for netgraph
to hook in without leaving the kernel. If you can supply an equally
effective way to hook into a serial device in such a way that it
appears to be a source/sink of bits then I don't care about
line disciplins, but until you have a suggested replacement then leave
them alone. There are MANY people using mpd with the netgraph ppp
moduel hooked directly to the serial port via the netgraph line
discipline.

What exact value of "MANY" are we talking about here, and do you
have any evidence that the systems in question will be updated
to FreeBSD-8.0-RELEASE or later ?

If, contrary to my expectation, that you can show a real market
here, then we should make a better interface than linedisc for
such hooks into serial ports.
