Interop with routing protocols... and networking in general... does
exist outside of the openwrt universe. In my case I am deeply
concerned about what happens against older, deployed versions of
Linuxes (and other OSes) with the new multicast-unicast bridge
conversion code in lede. Babel tends to use it, and I am also testing
(in lede!), as per the below, the dhcpv6-pd code, interop-ing with
several devices.

I'm really sorry that you hate cross posting so much. It must be
terrible to have to elide additional responses or deal with bounce
messages on every 20th email from me. And it must be wonderful to be
living in a world where all you have is openwrt/lede devices on the
network and modern kernels everywhere.
