mlx5-updates-2021-04-13 

mlx5 core and netdev driver updates
 
 1) E-Switch updates from Parav,
   1.1) Devlink parameter to control mlx5 metadata enablement for E-Switch
   1.2) Trivial cleanups for E-Switch code
   1.3) Dynamically allocate vport steering namespaces only when required
 
 2) From Jianbo, Use variably sized data structures for Software steering
 
 3) Several minor cleanups

esw_port_metadata: Eswitch port metadata state
----------------------------------------------
When applicable, disabling Eswitch metadata can increase packet rate
up to 20% depending on the use case and packet sizes.
Eswitch port metadata state controls whether to internally tag packets with
metadata. Metadata tagging must be enabled for multi-port RoCE, failover
between representors and stacked devices.
By default metadata is enabled on the supported devices in E-switch.
Metadata is applicable only for E-switch in switchdev mode and
users may disable it when NONE of the below use cases will be in use:
1. HCA is in Dual/multi-port RoCE mode.
2. VF/SF representor bonding (Usually used for Live migration)
3. Stacked devices
When metadata is disabled, the above use cases will fail to initialize if
users try to enable them.
- Show eswitch port metadata::
$ devlink dev param show pci/0000:06:00.0 name esw_port_metadata
pci/0000:06:00.0:
name esw_port_metadata type driver-specific
values:
cmode runtime value true
- Disable eswitch port metadata::
$ devlink dev param set pci/0000:06:00.0 name esw_port_metadata value false cmode runtime
- Change eswitch mode to switchdev mode where after choosing the metadata value::
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
mlx5 subfunction
================
mlx5 supports subfunction management using devlink port (see :ref:`Documentation/networking/devlink/devlink-port.rst <devlink_port>`) interface.
