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 v6: - various small fixes 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 drivers/net/intel/ice/ice_ethdev.c | 370 +++++++++++++++++++++++++++++ drivers/net/intel/ice/ice_rxtx.c | 21 ++ 2 files changed, 391 insertions(+) -- 2.43.0
