If this gets committed does this mean I can then remove the logic in dhcpcd which avoids the situation where there is an IPv6 router but you don’t get a useable IPv6 address? To avoid the lengthy timeouts, dhcpcd won’t add the IPv6 default route until a non link local address appears somewhere.

Attached is a patch to actually treat ICMP(v6) host/net/port unreachables
during TCP establishment in a way that doesn't cause ~75 second delays
waiting for multiple retransmits to all be reported as unreachable before
actually letting getaddrinfo(3) fall back to the next address.

Linux seems to handle this like this already.

Commitable?
