+Subject: [PATCH] ipv6: fix backtracking for throw routes
+
+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
