Add functions to create and destroy flow meter aso object.
This object only supports the range allocation. 64 objects are
allocated at a time, and there are two meters in each object.
Usually only one meter is allocated for a flow, so bitmap is used
to manage these 128 meters.

TC police action is mapped to hardware meter. As the index is unique
for each police action, add APIs to allocate or free hardware meter by
the index. If the meter is already created, increment its refcnt,
otherwise create new one. If police action has different parameters,
update hardware meter accordingly.

Add a separate API to create SQ and CQ for advanced steering

Since the mlx5_en API to create these resources is strongly coupled
with netdev channels and datapath elements, this API provides an
alternative for creating send queues that are used for ASO.

Currently the API allows creating channels with 2 wqbbs only - meaning
the support will be for a single ACCESS_ASO wqe with data at a time.

Currently, there are three eswitch modes, none, legacy and switchdev.
None is the default mode. Remove redundant none mode as eswitch mode

With this patch, there are two behavior changes:

1. Legacy becomes the default mode. When querying eswitch mode using

2. When disabling sriov, the eswitch mode will not change, only vfs

net: dsa: microchip: DSA Driver support for LAN937x

LAN937x is a Multi-Port 100BASE-T1 Ethernet Physical Layer switch
compliant with the IEEE 802.3bw-2015 specification. The device provides
100 Mbit/s transmit and receive capability over a single Unshielded
Twisted Pair (UTP) cable. LAN937x is successive revision of KSZ series
switch.
This series of patches provide the DSA driver support for
Microchip LAN937X switch through MII/RMII interface. The RGMII interface
support will be added in the follow up series.  LAN937x uses the most of
functionality of KSZ9477.

The LAN937x switch series family consists of following SKUs:

LAN9370:
  - 4 T1 Phys
  - 1 RGMII port

LAN9371:
  - 3 T1 Phys & 1 TX Phy
  - 2 RGMII ports

LAN9372:
  - 5 T1 Phys & 1 TX Phy
  - 2 RGMII ports

LAN9373:
  - 5 T1 Phys
  - 2 RGMII
  - 1 SGMII port

  - 6 T1 Phys
  - 2 RGMII ports

As stated by Russel King, miic_config() can be called as a result of
ethtool setting the configuration while the link is already up. Since
the speed is also set in this function, it could potentially modify
the current speed that is set. This will only happen if there is
no PHY present and we aren't using fixed-link mode.

Handle that by storing the current interface mode in the miic_port
structure and update the speed only if the interface mode is going to
be changed.
