[PATCH] ebtables: Cache a copy of the v3.16 kernel headers in the ebtables tree

[Pedro Alvarez <pedro.alvarez@codethink.co.uk>]

Hi everyone.

I've had some problems trying to build ebtables with the v3.19 kernels headers,
failing to build with the following error:

gcc -Wall -Wunused -Werror -fPIC -O3 -DPROGVERSION=\"2.0.10-4\"
-DPROGNAME=\"ebtables\" -DPROGDATE=\"December\ 2011\"
-D_PATH_ETHERTYPES=\"/etc/ethertypes\" -DEBTD_ARGC_MAX=50
-DEBTD_CMDLINE_MAXLN=2048 -DLOCKFILE=\"/var/lib/ebtables/lock\"
-DLOCKDIR=\"/var/lib/ebtables/\" -c -o extensions/ebt_ulog.o
extensions/ebt_ulog.c -Iinclude/
extensions/ebt_ulog.c:17:45: fatal error: linux/netfilter_bridge/ebt_ulog.h: No
such file or directory
 #include <linux/netfilter_bridge/ebt_ulog.h>
                                             ^

After some discussion on IRC we agreed there were 2 possible solutions:

 -1: Disable 'ulog' in the extensions/Makefile

 -2: Cache the headers needed in the ebtables tree.

I decided to go for 2, and here is the patch:

  Repo: git://git.baserock.org/delta/ebtables.git
  Branch: baserock/pedroalvarez/ebt_ulog-fix
  Sha1: 13747a56890cc710b2b4d420edc03a6c2714f40e

NOTE: I didn't want to send a diff, since it would be big and nonsense, but I
can do that if needed.

Regards!
