Current driver version is able to handle only one bridge at time.
Configuring two bridges on two different ports would end up shorting this
bridges by HW. To reproduce it:
ip l a name br0 type bridge
ip l a name br1 type bridge
ip l s dev br0 up
ip l s dev br1 up
ip l s lan1 master br0
ip l s dev lan1 up
ip l s lan2 master br1
ip l s dev lan2 up
Ping on lan1 and get response on lan2, which should not happen.
This happened, because current driver version is storing one global "Port VLAN
Membership" and applying it to all ports which are members of any
bridge.
To solve this issue, we need to handle each port separately.
This patch is dropping the global port member storage and calculating
membership dynamically depending on STP state and bridge participation.
Note: STP support was broken before this patch and should be fixed
separately.
