At one time I seriously considered doing an AXIP kernel driver based on the existing
IPIP system. I got as far as writing most of it, but lost it when I did a kernel
upgrade.
This was all about two years ago.
I seem to remember one of the big differences of AXIP to IPIP is the need to have a
look-
up table available to both the encapsulator and decapsulator, although for the life of
me,
I can't remember why :-(
These days I don't have access to the right hardware (2 PC's) to test such a system
which
means that writing a new version would be difficult.
