Merge branch 'mlxsw'

Jiri Pirko says:

====================
Introduce Mellanox Technologies Switch ASICs switchdev drivers

This patchset introduces Mellanox Technologies Switch driver infrastructure
and support for SwitchX-2 ASIC.

The driver is divided into 3 logical parts:
1) Bus - implements switch bus interface. Currently only PCI bus is
implemented, but more buses will be added in the future. Namely I2C
and SGMII.
(patch #2)
2) Driver - implemements of ASIC-specific functions.
Currently SwitchX-2 ASIC is supported, but a plan exists to introduce
support for Spectrum ASIC in the near future.
(patch #4)
3) Core - infrastructure that glues buses and drivers together.
It implements register access logic (EMADs) and takes care of RX traps
and events.
(patch #1 and #3)
====================

mlxsw: Introduce Mellanox SwitchX-2 ASIC support

Benefit from the previously introduced Mellanox Switch infrastructure and
add driver for SwitchX-2 ASIC. Note that this driver is very simple now.
It implements bare minimum for getting device to work on slow-path.
Fast-path offload functionality is going to be added soon.

mlxsw: Introduce Mellanox switch driver core

Add core components of Mellanox switch driver infrastructure.
Core infrastructure is designed so that it can be used by multiple
bus drivers (PCI now, I2C and SGMII are planned to be implemented
in the future). Multiple switch kind drivers can be registered as well.
This core serves as a glue between buses and drivers.
