[PATCH 0/6] Enable DCB/PFC support for ICE PMD

[Vladimir Medvedkin <vladimir.medvedkin@intel.com>]

This series introduces an initial implementation of DCB and PFC to the ICE PMD.
This includes adding support for TCs in ice_aq_set_mac_cfg() and asymmetric DCB/PFC configuration in base code.

Current implementation relies on current API and has a number of limitation and assumptions such as:

- Symmetric DCB configuration with respect to RX/TX, only dcb_rx_conf is used
- All TCs are configured equally with respect to BW they share
- No support for Low Latency TCs
- All existing queues are split evenly across TCs. Number of queues must be power of 2 and be no less than configured nb_tcs
- TX queues assigned to TCs the same way as RX queues

Vladimir Medvedkin (6):
  net/ice/base: add utility functions
  net/ice/base: make set MAC config TC aware
  net/ice/base: add supports for assymetric PFC
  net/ice: enable DCB support
  net/ice: enable PFC support
  net/ice: add PFC statistics
