Thanks for this patch. However, it unfortunately doesn't match the type
of minimal defconfig that we currently accept in Buildroot. Our
defconfig are meant to generate a minimal system, that boots up to a
Busybox shell prompt. All the rest should be left to user's
customization.

Why do you have a custom Busybox configuration? Isn't the default one
sufficient for your needs?

What if I don't want to use dnsmasq on this platform? If you want to
turn the BananaPi-R1 into a proper router, then we could have two
separate defconfig files:
lamobo_r1_defconfig -> really minimal
lamobo_r1_router_defconfig -> a router-like config
Also, maybe we can make this config file more minimal by only
keeping the non-commented lines?

Why ?

This patch is really *huge*. Unlike OpenWRT, we clearly do not want to
have large kernel patches to maintain in Buildroot. Having a patch
adding a Device Tree, or fixing minor stuff is OK. Having a patch
adding an entire subsystem + drivers is not OK.
So either find a way of downloading this patch, or make Buildroot point
to a Git tree where a complete Git tree of the kernel can be found, or
work with the upstream kernel to get this stuff merged.

If I understand correctly, this utility is only useful in combination
with the OpenWRT-specific switch configuration subsystem that was added
by your patch. Since this subsystem is not in the mainline kernel, I'm
really unsure we want to have the corresponding userspace utilities in
Buildroot.
Thanks,
Thomas
