ppp based on these patches for about 3 weeks with no downtime.
The original submitters comments:
Two features iijppp has over kernel ppp that I like are predictor1
compression and demand dialing. Here are a few bug fixes.
I expanded the priority queueing scheme and discovered it was broken
due to the assignment at ip.c line 300. All packets were being
queued at the same priority.
Fixing priority queueing broke predictor1 compression. Packets
were compressed before being queued and predictor1 worked as long
as the packets were popped off the queue in the same order they
were pushed onto the queue.
There were a few byte order problems in IP header tests also.
There is a recursion problem in SendLqrReport(). LcpClose() is
called when "Too many echo packets are lost" which winds up in
SendLqrReport() again. I believe the original intention was to
just stop the LQR timer with the call to StopLqr() but the side
effects hurt.

feature in the header type register, though it is required by the PCI spec.
This should correctly probe both functions of the Intel 82371FB chip,
without the need for a special case based on the device ID.
require kmem access. It is currently configured to call getloadavg(3),
which uses sysctl(2) to determine the load average, which is the
only reason some sendmails require kmem access.
1) The calculation didn't account for NMBCLUSTERS, so if a large number of
clusters was specified, it would leave little or no space for kernel
malloc.
2) It was bogusly restricted to v_page_count. This doesn't take into
account the sparseness of the malloc area and would have caused
problems on machines with small amounts of memory. It should probably
instead be changed to set the malloc limit to be constrained by
the amount of memory, but I didn't do this.
since setting up the DMA is too costly. Restructure for efficiency.
Pause the sequencer when a parity error occurs so that the kernel driver
knows during which phase the error was encountered.
. remove some unused variables
. declare worminit() right this time, it's actually extern (?)
. use wormminphys(), now that it's already there (hope i've got this right)
chipset. This does not attempt to do anything special with the timing
on the hope that the BIOS will have done the right thing already. The
actual interface from the wd driver to the new facility is not
implemented yet (this commit being an attempt at prodding someone else
to do it because looking at the wd driver always confuses the h*** out of me).
