switchdev: mrp: Remove SWITCHDEV_ATTR_ID_MRP_PORT_STAT

2021-02-17T10:02:29Z

commit 059d2a1004981dce19f0127dabc1b4ec927d202a upstream. Now that MRP started to use also SWITCHDEV_ATTR_ID_PORT_STP_STATE to notify HW, then SWITCHDEV_ATTR_ID_MRP_PORT_STAT is not used anywhere else, therefore we can remove it.

bridge: Add SWITCHDEV_FDB_FLUSH_TO_BRIDGE notifier

2020-09-15T20:21:47Z

so the switchdev can notifiy the bridge to flush non-permanent fdb entries for this port. This is useful whenever the hardware fdb of the switchdev is reset, but the netdev and the bridgeport are not deleted. Note that this has the same effect as the IFLA_BRPORT_FLUSH attribute.

switchdev: mrp: Extend switchdev API for MRP Interconnect

2020-07-14T20:46:42Z

Extend switchdev API to add support for MRP interconnect. The HW is notified in the following cases: SWITCHDEV_OBJ_ID_IN_ROLE_MRP: This is used when the interconnect role of the node changes. The supported roles are MIM and MIC. SWITCHDEV_OBJ_ID_IN_STATE_MRP: This is used when the interconnect ring changes it states to open or closed. SWITCHDEV_OBJ_ID_IN_TEST_MRP: This is used to start/stop sending MRP_InTest frames on all MRP ports. This is called only on nodes that have the interconnect role MIM.

bridge: mrp: Add support for role MRA

2020-06-01T18:56:11Z

A node that has the MRA role, it can behave as MRM or MRC. Initially it starts as MRM and sends MRP_Test frames on both ring ports. If it detects that there are MRP_Test send by another MRM, then it checks if these frames have a lower priority than itself. In this case it would send MRP_Nack frames to notify the other node that it needs to stop sending MRP_Test frames. If it receives a MRP_Nack frame then it stops sending MRP_Test frames and starts to behave as a MRC but it would continue to monitor the MRP_Test frames send by MRM. If at a point the MRM stops to send MRP_Test frames it would get the MRM role and start to send MRP_Test frames. Signed-off-by: Horatiu Vultur Signed-off-by: David S. Miller

bridge: mrp: Set the priority of MRP instance

2020-06-01T18:56:11Z

Each MRP instance has a priority, a lower value means a higher priority. The priority of MRP instance is stored in MRP_Test frame in this way all the MRP nodes in the ring can see other nodes priority. Signed-off-by: Horatiu Vultur Signed-off-by: David S. Miller

switchdev: mrp: Remove the variable mrp_ring_state

2020-05-22T23:17:15Z

Remove the variable mrp_ring_state from switchdev_attr because is not used anywhere. The ring state is set using SWITCHDEV_OBJ_ID_RING_STATE_MRP.

switchdev: mrp: Extend switchdev API to offload MRP

2020-04-27T18:40:25Z

Extend switchdev API to add support for MRP. The HW is notified in following cases: SWITCHDEV_OBJ_ID_MRP: This is used when a MRP instance is added/removed from the MRP ring. SWITCHDEV_OBJ_ID_RING_ROLE_MRP: This is used when the role of the node changes. The current supported roles are MRM and MRC. SWITCHDEV_OBJ_ID_RING_TEST_MRP: This is used when to start/stop sending MRP_Test frames on the mrp ring ports. This is called only on nodes that have the role MRM. In case this fails then the SW will generate the frames. SWITCHDEV_OBJ_ID_RING_STATE_STATE: This is used when the ring changes it states to open or closed. This is required to notify HW because the MRP_Test frame contains the field MRP_InState which contains this information. SWITCHDEV_ATTR_ID_MRP_PORT_STATE: This is used when the port's state is changed. It can be in blocking/forwarding mode. SWITCHDEV_ATTR_ID_MRP_PORT_ROLE: This is used when port's role changes. The roles of the port can be primary/secondary. This is required to notify HW because the MRP_Test frame contains the field MRP_PortRole that contains this information.

net: Remove switchdev_ops

2019-02-27T20:39:56Z
