orts. Another example is cross-chip hardware VLANs. Switch chips in-between interconnected bridge ports must also configure a given VLAN to allow packets to pass through them. In order to support that, this patchset introduces a non-intrusive notifier mechanism. It adds a notifier head in every DSA switch tree (the said fabric), and a notifier block in every DSA switch chip. When an even occurs, it is chained to all notifiers of the fabric. Switch chips can react accordingly if they are cross-chip capable. On a dynamic debug enabled system, bridging a port in a multi-chip fabric will print something like this (ZII Rev B board): # brctl addif br0 lan3 mv88e6085 0.1:00: crosschip DSA port 1.0 bridged to br0 mv88e6085 0.4:00: crosschip DSA port 1.0 bridged to br0 # brctl delif br0 lan3 mv88e6085 0.1:00: crosschip DSA port 1.0 unbridged from br0 mv88e6085 0.4:00: crosschip DSA port 1.0 unbridged from br0 Currently only bridging events are added. A patchset introducing support for cross-chip hardware bridging configuration in mv88e6xxx will follow right after. Then events for switchdev operations are next on the line. We should note that non-switchdev events do not support rolling-back switch-wide operations. We'll have to work on closer integration with switchdev for that, like introducing new attributes or objects, to benefit from the prepare and commit phases. ==================== Signed-off-by: David S.
