Hello David,

long time no see :)

I know it starts to be a bit late in the release cycle, but I think that
these 4 small bug-fixes are still worth being merged.

Patch 1 fixes a compatibility issue between our Distributed ARP Table
mechanism and the "early client detection" feature. Such issue creates
an inconsistency in the global translation table leading to user clients
not being reachable anymore. Fix provided by Simon Wunderlich.

Patch 2 is again provided by Simon Wunderlich and fixes another bug
related to the "early client detection" feature. The fix consists in
ensuring that temporary client entries not claimed by any originator
are properly purged instead of being stored all time long till
shutdown.

Patch 3 fixes the function used by the TT hash tables to detect
duplicate entries. At the moment two clients with the same MAC address
but lying in different VLANs are considered the same, while this should
not be the case. Bugfix by Marek Lindner.

Patch 4 fixes an invalid stack access in the batadv_dat_select_candidates()
function where a u32 pointer is accessed as it was a pointer to a
batadv_dat_entry struct (larger than u32). Bugfix provided by Sven
Eckelmann.


Please pull or let me know of any problem!

Thanks a lot,
	Antonio
