Subject: [PATCH net-next 07/10] selftests: mlxsw: extack: Test bridge creation with VXLAN

From: Ido Schimmel <idosch@...lanox.com>

Test that creation of a bridge (both VLAN-aware and VLAN-unaware) fails
with an extack when a VXLAN device with an unsupported configuration is
already enslaved to it.
