Looking at the code, it is not clear to me what would happen with: ip link add name br0 type bridge ip link set dev tsn0 master br0 ip link set dev br0 up ip link set dev tsn0 up ip link add name br1 type bridge ip link set dev tsn1 master br1 ip link set dev br1 up ip link set dev tsn1 up
Per design, it shall enable hardware forwarding when two ports are in the same brdev.
