[v2,6/7] batman-adv: bugfix for dat optimiziation patch

  Make sure that claiming of devices due to dat handling is only done
for non-local mac addresses. As dat is handled after the normal bla
code this does not break the roaming client scenario for bla.

What do you think about inverting the check and as jump to out when
batadv_is_my_client(bat_priv, addr, vid) is true?

The debug output change looks like it should be in patch 5/7.

Kind regards,

I believe this should actually be squashed into your PATCH 1/7? 

But this change is under discussion anyway ...

For future patches, please don't send bugfixes for your own patches within the 
same series separately but squash them in the right patches. :)

Thanks,
