I'll make a note about using CARLA.

It's pretty simple, none of the CRDA stuff is compatible with HSMM :)
Don't bother turning it on.

The general feeling I get from the linux-wireless guys is that part 97
operation should involve patches that are not intended for the
mainline tree, since that way you have to know what you're doing
before firing up a mesh network.  This may require us to distribute
firmware.
