------------------
From: Steven Barth <cyrus@openwrt.org>
commit 73ba57bfae4a1914f6a6dac71e3168dd900e00af upstream.
for throw routes to trigger evaluation of other policy rules EAGAIN needs to be propagated up to fib_rules_lookup similar to how its done for IPv4
A simple testcase for verification is:
ip -6 rule add lookup 33333 priority 33333 ip -6 route add throw 2001:db8::1 ip -6 route add 2001:db8::1 via fe80::1 dev wlan0 table 33333 ip route get 2001:db8::1
