Subject: [RFC PATCH net-next v4 0/6] Implement devlink-rate API and extend it

This patch series implements devlink-rate for ice driver. Unfortunately
current API isn't flexible enough for our use case, so there is a need to
extend it. New object type 'queue' is being introduced, and more functions
has been changed to non-static, to enable the driver to export current
Tx scheduling configuration.

This patch series is a follow up for this thread:
https://lore.kernel.org/netdev/20220704114513.2958937-1-michal.wilczynski@intel.com/T/#u

V4:
- changed static variable counter to per port IDA to
  uniquely identify nodes

V3:
- removed shift macros, since FIELD_PREP is used
- added static_assert for struct
- removed unnecessary functions
- used tab instead of space in define

V2:
- fixed Alexandr comments
- refactored code to fix checkpatch issues
- added mutual exclusion for RDMA, DCB


Ben Shelton (1):
  ice: Add function for move/reconfigure TxQ AQ command

Michal Wilczynski (5):
  devlink: Extend devlink-rate api with queues and new parameters
  ice: Introduce new parameters in ice_sched_node
  ice: Implement devlink-rate API
  ice: Export Tx scheduler configuration to devlink-rate
  ice: Prevent ADQ, DCB and RDMA coexistence with Custom Tx scheduler
