From f07232375d7f9384ec971d55343bf44ea1881fc4 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Wed, 28 Nov 2018 20:07:06 +0000 Subject: selftests: mlxsw: Add a test for VxLAN configuration with a VLAN-aware bridge Extend the existing VLAN-unaware tests with their VLAN-aware counterparts. This includes sanitization of invalid configuration and offload indication on the local route performing decapsulation and the FDB entries perform encapsulation.
