Subject: [PATCH net-next 00/12] mlxsw: More Spectrum-2 preparations

Hi,

This is the second and last set of preparations towards initial
Spectrum-2 support in mlxsw. It mainly re-arranges parts of the code
that need to work with both ASICs, but somewhat differ.

The first three patches allow different ASICs to register different set
of operations for KVD linear (KVDL) management. In Spectrum-2 there is
no linear memory and instead entries that reside there in Spectrum
(e.g., nexthops) are hashed and inserted to the hash-based KVD memory.

The fourth patch does a similar restructuring in the low-level multicast
router code. This is necessary because multicast routing is implemented
using regular circuit TCAM (C-TCAM) in Spectrum, whereas Spectrum-2 uses
an algorithmic TCAM (A-TCAM).

Next six patches prepare the ACL code for the introduction of A-TCAM in
follow-up patch sets.

Last two patches allow different ASICs to require different firmware
versions and add two resources that need to be queried from firmware by
Spectrum-2 specific code.

Jiri Pirko (12):
  mlxsw: spectrum_kvdl: Push out KVD linear management into ops
  mlxsw: spectrum_kvdl: Pass entry type to alloc/free
  mlxsw: spectrum_kvdl: Pass entry_count to free function
  mlxsw: spectrum_mr_tcam: Push Spectrum-specific operations into a
    separate file
  mlxsw: spectrum_acl: Split TCAM handling 3 ways
  mlxsw: spectrum_acl: Add tcam init/fini ops
  mlxsw: spectrum_acl: Convert mlxsw_afk_create args to ops
  mlxsw: spectrum_acl: Move block items encoding into Spectrum op
  mlxsw: reg: Add priority field for PTCEV2 register
  mlxsw: spectrum_acl: Implement priority setting for rules inserted to
    TCAM
  mlxsw: spectrum: Prepare for multiple FW versions for Spectrum and
    Spectrum-2
  mlxsw: resources: Add couple of Spectrum-2 KVD resources
