IPv6 flood correlating with bpdus not being received

[rubensfig]

Expected Behavior

When a switch has a bridge configured with ports and xSTP is enabled at the bridge, both the Kernel and mstpd must be able to block the correct port, considering correct configuration.

Actual Behavior

With the configuration described above, baseboxd is sometimes failing to receive the required Bridge PDUs to set STP state. This is due to IPv6 MLD packets being flooded, overflowing the OpenFlow channel and impeding baseboxd to receive the relevant traffic. This can be solved by removing the FF02: ACL rule.

Steps to Reproduce the Problem

ip link add name swbridge type bridge vlan_filtering 1 stp_state 1
ip link set port1 master swbridge
ip link set port2 master swbridge
ip link set port1 up
ip link set port2 up
ip link set swbridge up
