From 9d15dceb8a36919897d52ec8e4a6e6efa57f9f19 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 20 Dec 2018 19:42:25 +0000 Subject: selftests: mlxsw: Add a test case for L3 VNI Previous patch added the ability to offload a VXLAN tunnel used for L3 VNI when it is present in the VLAN-aware bridge before the corresponding VLAN interface is configured. This patch adds a test case to verify that. Signed-off-by: Ido Schimmel Signed-off-by: David S.
