If you like, I can send those too. I4L is still in use on some sides and here is no 100% replacement (net via RAW IP mode, terminal via X.75). This week I got some question from a big retail chain in Germany about migration. I never know that they are using this stuff (for initial setup of remote shops). So I would not drop i4l yet, maybe we should propose this for 2018. I4L is not so usefull for NT mode, which is very popular nowadays for gateways into the new full IP world. Some design ins with mISDN here, mostly in the embedded area. > > My main motivation was to not have to fix up the ippp implementation > when I move the compat ioctl handler from fs/compat_ioctl.c > into drivers/net/ppp/ppp_generic.c, but I guess I can do that > anyway as it seems that i4l never worked properly in compat mode. > > Arnd > > > > >
