From ef27f153302b9f8296f5a8c71d08ae7392e721de Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Wed, 10 Jan 2018 15:38:42 +0100 Subject: [PATCH] kernel: allow disabling multicast routing support Multicast routing support is not needed in most setups, and increases the size of the kernel considerably (>10K after LZMA). Add a config switch to allow disabling it.
