Subject: [PATCH v3 net-next 20/20] selftests: Add version of router_multipath.sh using nexthop objects
Date: Fri, 7 Jun 2019 16:06:10 -0700 [thread overview]
Message-ID: <20190607230610.10349-21-dsahern@kernel.org> (raw)
In-Reply-To: <20190607230610.10349-1-dsahern@kernel.org>
From: David Ahern <dsahern@gmail.com>
Add a version of router_multipath.sh that uses nexthop objects for
routes.
Ido requested a version that does not cause regressions with mlxsw
testing since it does not support nexthop objects yet.
