Subject: [PATCH net-next 0/9] mlxsw: spectrum_cnt: Expose counter resources

From: Ido Schimmel <idosch@...lanox.com>

Jiri says:

Capacity and utilization of existing flow and RIF counters are currently
unavailable to be seen by the user. Use the existing devlink resources
API to expose the information:

$ sudo devlink resource show pci/0000:00:10.0 -v
pci/0000:00:10.0:
  name kvd resource_path /kvd size 524288 unit entry dpipe_tables none
  name span_agents resource_path /span_agents size 8 occ 0 unit entry dpipe_tables none
  name counters resource_path /counters size 79872 occ 44 unit entry dpipe_tables none
    resources:
      name flow resource_path /counters/flow size 61440 occ 4 unit entry dpipe_tables none
      name rif resource_path /counters/rif size 18432 occ 40 unit entry dpipe_tables none

Jiri Pirko (9):
  mlxsw: spectrum_cnt: Query bank size from FW resources
  selftests: spectrum-2: Adjust tc_flower_scale limit according to
    current counter count
  mlxsw: spectrum_cnt: Move sub_pools under per-instance pool struct
  mlxsw: spectrum_cnt: Add entry_size_res_id for each subpool and use it
    to query entry size
  mlxsw: spectrum_cnt: Expose subpool sizes over devlink resources
  mlxsw: spectrum_cnt: Move config validation along with resource
    register
  mlxsw: spectrum_cnt: Consolidate subpools initialization
  mlxsw: spectrum_cnt: Expose devlink resource occupancy for counters
  selftests: mlxsw: Add tc action hw_stats tests
