Message-Id: <254e52c2f5694e96a86e622337637ff1b9c5e12b.1530204784.git.petrm@mellanox.com> Date: Thu, 28 Jun 2018 18:56:39 +0200 From: Petr Machata <petrm@...lanox.com> To: netdev@...r.kernel.org, linux-kselftest@...r.kernel.org Cc: davem@...emloft.net, shuah@...nel.org Subject: [PATCH net-next 4/4] selftests: forwarding: mirror_gre_changes: Fix waiting for neighbor When running the test on soft devices, there's no mechanism to gratuitously start resolving the neighbor for remote tunnel endpoint. So instead of passively waiting, wait for the device to be up, and then probe the neighbor with a ping.
