Introduce devlink infrastructure Introduce devlink infrastructure for drivers to register and expose to userspace via generic Netlink interface. There are two basic objects defined: devlink - one instance for every "parent device", for example switch ASIC devlink port - one instance for every physical port of the device. This initial portion implements basic get/dump of objects to userspace. Also, port splitter and port type setting is implemented. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

devlink: add shared buffer configuration Define userspace API and drivers API for configuration of shared buffers. Four basic objects are defined: shared buffer - attributes are size, number of pools and TCs pool - chunk of sharedbuffer definition, it has some size and either static or dynamic threshold port pool threshold - to set per-port threshold for each pool port tc threshold bind - to bind port and TC to specified pool with threshold.

Introduce devlink infrastructure Introduce devlink infrastructure for drivers to register and expose to userspace via generic Netlink interface. There are two basic objects defined: devlink - one instance for every "parent device", for example switch ASIC devlink port - one instance for every physical port of the device. This initial portion implements basic get/dump of objects to userspace. Also, port splitter and port type setting is implemented. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

devlink: add shared buffer configuration Define userspace API and drivers API for configuration of shared buffers. Four basic objects are defined: shared buffer - attributes are size, number of pools and TCs pool - chunk of sharedbuffer definition, it has some size and either static or dynamic threshold port pool threshold - to set per-port threshold for each pool port tc threshold bind - to bind port and TC to specified pool with threshold.
