why not? The packet definition header has been put in UAPI, so I need that

figured that would be the right position.

OK, I will change that.

OK.
I can rework and resend this particular patch - probably to linux wireless. If
the other patches are ok, would you guys merge the first two patches to net-
next then?
Thanks,
Simon
