>Description:

I was playing about with the kernel mode PPP code, and had forgotten
to compile kernel mode PPP support into the kernel I was running.
Never fear, I had a if_ppp lkm handy for that kernel, so I modloaded
it.

pppd recognized that the kernel ppp code had been installed, but gave the
following error:

Feb 11 02:27:27 precipice pppd[862]: pppd 2.2.0 started by pst, uid 0
Feb 11 02:27:31 precipice pppd[862]: ioctl(TIOCSETD): Operation not supported by device

A quick perusal of the kernel source shows pppasyncattach appearing as
the argument to a PSEUDO_SET macro, but there are other attach routines
in if_ppp.c,  so my totally unreasearched GUESS is that one of the other
PSEUDO_SET vectors is wiping out the first, or some such rot (sorry, I
didn't look).

I worked around the problem by hard-compiling kernel mode ppp back into
that kernel, which suggested to me that it's an LKM initialization problem
only.

Feb 11 02:46:46 precipice pppd[250]: pppd 2.2.0 started by pst, uid 0
Feb 11 02:46:49 precipice pppd[250]: Connect: ppp0 <--> /dev/cuaa1

Feb 11 02:46:53 precipice pppd[250]: remote IP address 206.171.128.66



>How-To-Repeat:

Run kernel with no kernel ppp (pppd) support.
modload /lkm/if_ppp.o
pppd /dev/cuaa1 115200 ...other options...

get "ioctl(TIOCSETD): Operation not supported by device" message
