net: dsa: add switch notifier Add a notifier block per DSA switch, registered against a notifier head in the switch fabric they belong to. This infrastructure will allow to propagate fabric-wide events such as port bridging, VLAN configuration, etc. If a DSA switch driver cares about cross-chip configuration, such events can be caught.

net: dsa: add notifier for ageing time This patch keeps the port-wide ageing time handling code in dsa_port_ageing_time, pushes the requested ageing time value in a new switch fabric notification, and moves the switch-wide ageing time handling code in dsa_switch_ageing_time. This has the effect that now not only the switch that the target port belongs to can be programmed, but all switches composing the switch fabric. For the moment, keep the current behavior and ignore other switches.

net: dsa: add notifier for ageing time This patch keeps the port-wide ageing time handling code in dsa_port_ageing_time, pushes the requested ageing time value in a new switch fabric notification, and moves the switch-wide ageing time handling code in dsa_switch_ageing_time. This has the effect that now not only the switch that the target port belongs to can be programmed, but all switches composing the switch fabric. For the moment, keep the current behavior and ignore other switches.

net: dsa: introduce bridge notifier A slave device will now notify the switch fabric once its port is bridged or unbridged, instead of calling directly its switch operations. This code allows propagating cross-chip bridging events in the fabric. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net: dsa: add FDB notifier Add two new DSA_NOTIFIER_FDB_ADD and DSA_NOTIFIER_FDB_DEL events to notify not only a single switch, but all switches of a the fabric when an FDB entry is added or removed. For the moment, keep the current behavior and ignore other switches.

net: dsa: add switch notifier Add a notifier block per DSA switch, registered against a notifier head in the switch fabric they belong to. This infrastructure will allow to propagate fabric-wide events such as port bridging, VLAN configuration, etc. If a DSA switch driver cares about cross-chip configuration, such events can be caught.
