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.

devlink: implement shared buffer occupancy monitoring interface User needs to monitor shared buffer occupancy. For that, he issues a snapshot command in order to instruct hardware to catch current and maximal occupancy values, and clear command in order to clear the historical maximal values. Also port-pool and tc-pool-bind command response messages are extended to carry occupancy values.

net/devlink: Add E-Switch mode control Add the commands to set and show the mode of SRIOV E-Switch, two modes are supported: * legacy: operating in the "old" L2 based mode (DMAC --> VF vport) * switchdev: the E-Switch is referred to as whitebox switch configured using standard tools such as tc, bridge, openvswitch etc. To allow working with the tools, for each VF, a VF representor netdevice is created by the E-Switch manager vendor device driver instance (e.g PF).

devlink: Add E-Switch inline mode control Some HWs need the VF driver to put part of the packet headers on the TX descriptor so the e-switch can do proper matching and steering. The supported modes: none, link, network, transport.
