[Antonio Quartulli]

Hello David,

this is a batch of patches intended for net-next.

In this patchset you have mostly cleanups and small corrections to issues
reported by checkpatch.

One notable change is the addition of the DEBUG_FS dependency to the
BATMAN_ADV_DEBUG symbol by Markus Pargmann. We add this dependency because all
the information provided by the DEBUG feature is accessible only through
debugfs.


Please pull or let me know of any problem!

Thanks a lot,
	Antonio

[B.A.T.M.A.N.] [PATCH 02/15] batman-adv: remove obsolete variable primary_iface from orig_node

[Antonio Quartulli]

From: Simon Wunderlich <sw@simonwunderlich.de>

This variable became obsolete when changing to the new bonding mechanism
based on the multi interface optimization. Since its not used anywhere,
remove it.

[B.A.T.M.A.N.] [PATCH 12/15] batman-adv: clear control block of received socket buffers

[Antonio Quartulli]

From: Martin Hundebøll <martin@hundeboll.net>

Since other network components (and some drivers) uses the control block
provided in skb's, the network coding feature might wrongly assume that
an SKB has been decoded, and thus not try to code it with another packet
again. This happens for instance when batman-adv is running on a bridge device.

Fix this by clearing the control block for every received SKB.

Introduced by 3c12de9a5c756b23fe7c9ab332474ece1568914c

[Antonio Quartulli]

From: Markus Pargmann <mpa@pengutronix.de>

BATMAN_ADV_DEBUG is using debugfs files for the debugging log. So it
depends on DEBUG_FS which is missing as dependency in the Kconfig file.
