Option to forward BPDU (Ethernet control class) frames
Currently, a NORMAL action bridge drops reserved-multicast-mac addresses;
01-80-c2-00-00-[f0:ff]. A node that does not implement STP should have an
option to forward such frames.
This commit proposes to have a configuration option to allow forwarding of
BPDU class frames. To ensure backward compatibility, this option is
disabled by default.
This config can be set using bridge's other-config column, for e.g
ovs-vsctl set bridge br0 other-config:forward-bpdu=true
Changing this option can revalidate all flows in a software-OVS
implementation (ofproto-dpif)
--------
unit tests:
------------
make config changes, test runtime behavior
-- test runtime behavior --
continuously send packets to br0 with dest-mac=01:80:c2:00:00:00
ovs-dpctl dump-flows br0
ovs-vsctl set bridge br0 other-config:forward-bpdu=true
ovs-dpctl dump-flows br0
ovs-vsctl set bridge br0 other-config:forward-bpdu=false
ovs-dpctl dump-flows br0
ovs-vsctl set bridge br0 other-config:forward-bpdu=true
ovs-dpctl dump-flows br0
ovs-vsctl remove bridge br0 other-config forward-bpdu=true
ovs-dpctl dump-flows br0
