[PATCH v5 0/3] Enable DCB/PFC support for ICE PMD

[Vladimir Medvedkin]

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

v5:
- drop base code patches
- rebase on top of the next-net

v4:
- fix more endianness

v3:
 - ice_get_tc_by_up() is renamed to ice_get_tc_by_priority() for better clarity
 - added ice_aq_set_mac_pfc_cfg(). Old ice_aq_set_mac_cfg() is a wrapper around a new function to keep better backward compatibility with an old code
 - removed rte_memcpy() and memcry() with direct assignment
 - addressed various style-related comments

v2:
 - fix spelling
 - replace rte_memcpy with memcpy()
 - fix endianness in several places

Vladimir Medvedkin (3):
  net/ice: enable DCB support
  net/ice: enable PFC support
  net/ice: add PFC statistics
