This is all going in the wrong direction. Link-local addresses are not optional on an interface, all IPv6 enabled interfaces are required to have one:
The original patch did indeed disable the generation of the link-local address, but that patch was rejected. It sounds like the right approach here is to provide two new addressing modes: IN6_ADDR_GEN_MODE_RANDOM_LL_TOKEN IN6_ADDR_GEN_MODE_STABLE_PRIVACY_LL_TOKEN which would form the link-local address from the token passed in via IFLA_INET6_TOKEN, but would form non-link-local addresses (e.g., global addresses) via the specified means (either random or stable privacy). I haven't looked at how to do that yet though. _______________________________________________ Linux-mediatek mailing list Linux-mediatek@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-mediatek
