Thanks for the patch. We're discussing how to reach to this code properly
in the lab now. Although we will probably have to modify so it's compliant
with the RFC, by checking if a ndisc_send_ns() has already been queued
within rt->rt6i_idev->cnf.rtr_probe_interval, otherwise it could flood the
network with neighbor discoveries.

Thanks for testing, I can't reproduce the deadlock you reported here.

Note that the original code didn't check rtr_probe_interval either.
