  Hello David,

here you have our patchset for net-next/linux-3.15.
They are 16 patches but most of them are just small cleanups and kerneldoc
improvements.

The only big change is the one from patch 8 to 13 by Linus Lüssing that
introduces a new multicast packets optimisation. This new component aims to
reduce the air overhead by sending multicast packets as bat-unicast
when only one destination exists or by dropping them directly at the source if
the multicast group is totally empty.

In patch 11 Linus introduces an atomic_t variable, that like others that we
already have is only object of write and read, thus making the atomic
characteristic totally useless.
Unfortunately this is part of our sysfs framework, that helps the developer to
introduce new knobs by using few macros only. For this reason we decided to keep
Linus' new knob for now, but I'd like to let you know that we are in the process
of re-working such framework in order to convert all the current (useless)
atomic_t to boolean in one go.


Please pull or let me know of any problem!

Thanks a lot,
	Antonio
