Looking to create a PR for VRF support and the building of the kmod-vrf package. The feature adds a handful of bytes to the kernel image size (<100 bytes in testing) and once the kmod package is installed this allows for some very sophisticated routing scenarios.
Question is - where is the best place to set kernel options like the NET_L3_MASTER_DEV kernel option? There seem to be a number of places where this option could live. I can easily generate a standalone .config to build locally and test this but I am not sure where the official build system prefers these options to be placed.
I would like to create a PR adding VRF support to the standard kernel (on devices that are not seriously space-constrained).
