From: Danielle Ratson <danieller@nvidia.com>

Test that each veto that was added in the previous patch, is indeed
vetoed.

$ ./q_in_q_veto.sh

TEST: create 802.1ad vlan upper on top of a front panel [ OK ]
TEST: create 802.1ad vlan upper on top of a bridge port [ OK ]
TEST: create 802.1ad vlan upper on top of a lag [ OK ]
TEST: create 802.1ad vlan upper on top 802.1q bridge [ OK ]
TEST: create 802.1ad vlan upper on top 802.1ad bridge [ OK ]
TEST: create 802.1q vlan upper on top 802.1ad bridge [ OK ]
TEST: create vlan upper on top of front panel enslaved to 802.1ad bridge
[ OK ]
TEST: create vlan upper on top of lag enslaved to 802.1ad bridge [ OK ]
TEST: enslave front panel with vlan upper to 802.1ad bridge [ OK ]
TEST: enslave lag with vlan upper to 802.1ad bridge [ OK ]
TEST: IP address addition to 802.1ad bridge [ OK ]
TEST: switch bridge protocol [ OK ]
