Subject: kernel: make lwtunnel support optional
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=412dc26c99beeeeace3e56321fc392e590f4144d;p=openwrt%2Fstaging%2Fldir.git

kernel: make lwtunnel support optional

Not everyone will want to bloat their kernel by 24 kiB for such a niche
feature.

Fixes: a1a7f3274e0ed27511d45f62ee20281d8d57c7af "kernel: enable SRv6 support by
enabling lwtunnel"
