no. The current situation was a conclusion that we had massive changes
inside the generic 6LoWPAN branch (net/6lowpan) which is used by
ble/802.15.4 . For easier applying without conflicts marcel offers his
help to apply everything and I think he has actual a nice setup with:

 - some creat testing evironment which checks if patch apply and run
   tests on it.

 - klick one button to send "thanks applied" mail and apply the patch on
   his bluetooth branch and send a push. (maybe on his iPad ;-))

Currently I don't have such setup environment, but I need something like
that. When the time allows then I will try to build something like that.


What I do now is to have a private queue, if Marcel doesn't repsond ~2
weeks after the "Acked-by" then I will send a "ping". I think every
maintainer have a timeslot to making his/her "rounds" on the mailinglist
to grab patches. I am not forwarding the patches to marcel, he will
apply the patches from linux-wpan or netdev mailinglist.

The time will come when linux-wpan have his own repository and send then
pull-request to Marcel (if there are too many shared code between
802.15.4 and bt) or netdev.
