Date: Tue, 14 Apr 2020 13:26:10 +0200 [thread overview] Message-ID: <20200414112618.3644-2-horatiu.vultur@microchip.com> (raw) In-Reply-To: <20200414112618.3644-1-horatiu.vultur@microchip.com> Add new nested netlink attribute to configure the MRP. These attributes are used by the userspace to add/delete/configure MRP instances and by the kernel to notify the userspace when the MRP ring gets open/closed. MRP nested attribute has the following attributes: IFLA_BRIDGE_MRP_INSTANCE - the parameter type is br_mrp_instance which contains the instance id, and the ifindex of the two ports. The ports can't be part of multiple instances. This is used to create/delete MRP instances. IFLA_BRIDGE_MRP_PORT_STATE - the parameter type is u32. Which can be forwarding, blocking or disabled. IFLA_BRIDGE_MRP_PORT_ROLE - the parameter type is br_mrp_port_role which contains the instance id and the role. The role can be primary or secondary. IFLA_BRIDGE_MRP_RING_STATE - the parameter type is br_mrp_ring_state which contains the instance id and the state. The state can be open or closed. IFLA_BRIDGE_MRP_RING_ROLE - the parameter type is br_mrp_ring_role which contains the instance id and the ring role. The role can be MRM or MRC. IFLA_BRIDGE_MRP_START_TEST - the parameter type is br_mrp_start_test which contains the instance id, the interval at which to send the MRP_Test frames, how many test frames can be missed before declaring the ring open and the period which represent for how long to send the test frames. IFLA_BRIDGE_MRP_RING_OPEN - the parameter type is u32 and has a value of 1 if the port stopped receiving test frames and a value 0 is started to receive them. This attribut is used by the kernel to notify the userspace when the ring gets open or closed. Also add the file include/uapi/linux/mrp_bridge.h which defines all the types used by MRP that are also needed by the userpace.
