Subject: [PATCH net-next 07/13] switchdev: mrp: Extend switchdev API to offload MRP
Date: Mon, 20 Apr 2020 17:09:41 +0200 [thread overview]
Message-ID: <20200420150947.30974-8-horatiu.vultur@microchip.com> (raw)
In-Reply-To: <20200420150947.30974-1-horatiu.vultur@microchip.com>
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.
