In presence of LLVM in the base, it looks, that we should generate
native code from IPFW bytecodes, without intermediate C code :)
Looks doeable!

I still don't understand why it should
I can't help but remember when "someone" wrote an ipfw rule compiler -
ie, take ipfw ruleset, generate C code.
Maybe someone should write one and open source it this time.. :)

Hi Gleb,
Thanks for your patch, i applied it and its production already.
i had to stop mpd, and once started it i saw that all home routers
connected immediatly.
most of them don't use mppc, so I wonder why this problem happend in the
first place.

If I understand correctly, this would require netmap to catch every

Hello,
I'm using PPP with an USB UMTS stick (Huawei E1750). The speed for
upload and download can be measured with, for example, pages like:
http://www.speedtest.net/
the results vary of course a bit, but usually they are between
1 and 4 Mbps;
how those values fit with the speed of the device /d
Hi,
do you use dummynet?
what is the server hardware configuration and tunings you did to acheive
10Gbps ?

okay,
i reverted back to my original ng_mppc.c.
btw: there an alternative module in here: http://www.mavhome.dp.ua/MPPC/
maybe this helps..
