I ran into this too (when trying to ping Contiki). Tony then pointed
out on IRC that you had once done something about this issue but the
patches never made it upstream.

What's the status of your patches ? Do you plan to submit them to
net-next ?

One more missing feature in this area would be decompressing IPv6
addresses based on short IEEE 802.15.4 addresses, according to
RFC6282, section 3.2.2.

By the way, when trying to get Linux to respond to a ping from
Contiki, I also found a problem with flow label decompression.
Here's a quick and dirty patch that makes things work:

https://github.com/wpwrak/ben-wpan-linux/commit/4b634d5591104354b15cbc6503cddde33961b4db

Note that the code there should do more checking, to avoid trying to
pull more data from the skb than what is actually there. I also
didn't review the logic of compression modes I'm not using.
