Subject: [PATCH net-next 1/2] net/ipv6: Handle onlink flag with multipath routes

From: David Ahern <[email-masked]>
Date: Tue, 13 Mar 2018 08:40:09 -0700

For multipath routes the ONLINK flag is specified per nexthop in rtnh_flags
(as opposed to rtm_flags for unicast routes). Update ip6_route_multipath_add
to set fc_flags based on rtnh_flags.

Fixes: fc1e64e1092f ("net/ipv6: Add support for onlink flag")
