Message-Id: <20180213163736.1538-2-dsahern@gmail.com> Date: Tue, 13 Feb 2018 08:37:33 -0800 From: David Ahern <dsahern@...il.com> To: netdev@...r.kernel.org Cc: idosch@...lanox.com, David Ahern <dsahern@...il.com> Subject: [PATCH net-next 1/4] selftests: fib_tests: simplify ip commands in a namespace 'ip netns exec testns ip' is more efficiently handled using 'ip -netns'; runs the ip command after switching the namespace and avoids an exec.
