Subject: kernel: add kmod-vrf
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=45d541bb409355f090b971d96ebebd8610ef84a7;p=openwrt%2Fstaging%2Fdangole.git

kernel: add kmod-vrf

Add option to compile kmod-vrf, support for Virtual Routing and
Forwarding (Lite).

This module depends on NET_L3_MASTER_DEV, which is a boolean kernel
option, so we need to create a configuration option also for this, and
make kmod-vrf depend on it.
