batman-adv: enable MCAST by default at compile time
Commit Message
Thanks to rigorous testing in wireless community mesh networks several
issues with multicast entries in the translation table were found and
fixed in the last 1.5 years. Now we see the first larger networks
(a few hundred nodes) with a batman-adv version with multicast
optimizations enabled arising, with no TT / multicast optimization
related issues so far.
Therefore it seems safe to enable multicast optimizations by default not
only in kernel module builds but also for in-kernel builds.

I have now queued it up for the upcoming net-next PR. This patch should be
merged after we released batman-adv 2018.4. But my original patch to disable
the MCAST optimization by default [1] for 2018.4 was already reverted. The
2018.4 release will therefore still have MCAST enabled by default for the out-
of-tree module.
Thanks,
Sven

This option enables the multicast optimisation which aims to
reduce the air overhead while improving the reliability of
