at least I can see:;a=blob;f=target/linux/generic/patches-3.19/670-ipv6-allow-rejecting-with-source-address-failed-policy.patch;h=f32458df30ad466d4e3ac8224cbec1bd074b43ec;hb=35d90ba52069c96afd1a74600b91499e5feed0e0

I was last refreshed on Tue Mar 30 22:01:27 2021 +0100
and says:

"RFC6204 L-14 requires rejecting traffic from invalid addresses with
 ICMPv6 Destination Unreachable, Code 5 (Source address failed ingress/
 egress policy) on the LAN side, so add an appropriate rule for that."

But that is just guessing...

bye, Bastian
