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
