Subject: [PATCH net 1/2] ipv6: Fix RTA_MULTIPATH with nexthop objects

From: David Ahern <[email-masked]>
Date: Tue, 3 Sep 2019 15:22:12 -0700

From: David Ahern <[email-masked]>

A change to the core nla helpers was missed during the push of
the nexthop changes. rt6_fill_node_nexthop should be calling
nla_nest_start_noflag not nla_nest_start. Currently, iproute2
does not print multipath data because of parsing issues with
the attribute.

Fixes: f88d8ea67fbd ("ipv6: Plumb support for nexthop object in a fib6_info")
