Yes, on top of Tony's patches (below), I've mainlined patches which
enable what Tony says above.
You have to change the compression type to IPV6 on the Contiki side, but
that just handles sending. You have to also make a mod to make Contiki
to _accept_ compressed packets (because changing the compression type to
IPV6 on the contiki side removes the ability to _receive_ compressed
packets, which Linux sends)[1]. When I get some more time, I'll get this
fixed in the kernel.

The easiest way to grab Tony's patches is from the beaglebord.org kernel:
https://github.com/beagleboard/kernel/tree/3.8/patches/6lowpan
You can change the branch to get it for different kernel versions. It's
also on my list to get this stuff mainlined, (unless Tony gets to it first).

[1] I can send this when I get back to my other development machine, but
it's easy enough to find in the source if you want to do it before then.
