Subject: [PATCH net-next v3 0/9] net: ethernet: ti: ale: add static configuration 

Hi All,

As existing, as newly introduced CPSW ALE versions have differences in 
supported features and ALE table formats. Especially it's actual for the
recent AM65x/J721E/J7200 and future AM64x SoCs, which supports more
features like: auto-aging, classifiers, Link aggregation, additional HW
filtering, etc.

The existing ALE configuration interface is not practical in terms of 
adding new features and requires consumers to program a lot static
parameters. And any attempt to add new features will case endless adding
and maintaining different combination of flags and options. Because CPSW
ALE configuration is static and fixed for SoC (or set of SoC), It is
reasonable to add support for static ALE configurations inside ALE module.

This series introduces static ALE configuration table for different ALE 
variants and provides option for consumers to select required ALE
configuration by providing ALE const char *dev_id identifier (Patch 2).
And all existing driver have been switched to use new approach (Patches 3-6).

After this ALE HW auto-ageing feature can be enabled for AM65x CPSW ALE 
variant (Patch 7).

Finally, Patches 8-9 introduces tables to describe the ALE VLAN entries 
fields as the ALE VLAN entries are too much differ between different TI
CPSW ALE versions. So, handling them using flags, defines and get/set
functions are became over-complicated.

Patch 1 - is preparation patch

Changes in v3:
- fixed comment for Patch 2

Changes in v2:
- fixed sparse warnings

v2: https://lore.kernel.org/patchwork/cover/1301684/
v1: https://lore.kernel.org/patchwork/cover/1301048/
