Subject: [PATCH net-next 7/7] selftests: fib_nexthops: Test IPv6 route with group after replacing IPv4 nexthops
From: Ido Schimmel <idosch@...dia.com>
Test that an IPv6 route can not use a nexthop group with mixed IPv4 and
IPv6 nexthops, but can use it after replacing the IPv4 nexthops with
IPv6 nexthops.
Output without previous patch:
# ./fib_nexthops.sh -t ipv6_fcnal_runtime
