The new code to enable IPv6 extended error reporting will cause an error ("Protocol not available (errno=92)") if trying to enable that setsockopt() option on an IPv4-only socket. Fix: pass sock->info.af to set_sock_extended_error_passing(), only apply to AF_INET6 sockets. To make that work, ensure that sock->info.af is set to not only the value coming from config (which might be AF_UNSPEC) but to the actual value used in socket creation (credits: Arne Schwabe). Add comments to make explicit that the asymmetry here (IPv4 extended socket error reporting is enabled on all sockets) is intentional.
