Custom kernel / mvrp setup

Hi,

I just bought a couple old zyxel access points (NWA 1100-NH) for my home network. I just fleshed out the basis of a dynamic vlan setup and I'm exploring the ways to streamline the addition of new vlans.
One appealing feature is MVRP, which I could enable on the mikrotik router I use, but I've found close to nothing regarding openwrt.

It looks like I need to compile a custom kernel (CONFIG_VLAN_8021Q_MVRP I guess), and I'm not sure where this is going to bring me :slightly_smiling_face:
I'm afraid this could prevent me from using the modules installable with opkg : is that a risk that I could somehow mitigate ?

Now I just cloned openwrt repo, did make menuconfig and make kernel_menuconfig, saved my changes but not sure I should proceed further. The number of changes from the diff below are quite many, and I think I would like to keep only the 2 highlighted below.

I'll try some things but any feedback welcome.
