From: Matthias Schiffer Date: Wed, 10 Jan 2018 14:38:42 +0000 (+0100) Subject: kernel: allow disabling multicast routing support X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ef27f153302b9f8296f5a8c71d08ae7392e721de;p=openwrt%2Fstaging%2Fneocturne.git 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.
