1) boot, ping no vlan

# ip link add name br0 type bridge
# echo 0 > /sys/class/net/br0/bridge/default_pvid
# ip link set dev eth2 master br0
# ip link set dev eth0 master br0
# ip link set dev eth1 master br0
# ifconfig br0 192.168.1.2

*Note*: I've had to disable default_pvid as otherwise linux Bridge adds
and offloads default vlan 1, but default configuration for CPSW driver is vid 0.
+  CPSW specific - it can't untag packets for P0.
Another option I've found:
# ip link set dev br0 type bridge vlan_filtering 1.
but anyway, I've found it confusing that Linux bridge adds default vlan when vlan_filtering == 0

There are three different configurations here you need to worry about,
with respect to vlans:

# CONFIG_VLAN_8021Q is not set

So you don't have any vlan support in the kernel.

CONFIG_VLAN_8021Q=y, vlan_filtering = 0

So you have vlans, but filtering is off

CONFIG_VLAN_8021Q=y, vlan_filtering = 1

So you have vlans, and filtering is on.

Even with vlan_filtering off, the bridge still does a little with
vlans.

And you need all three to work correctly.
