Once packets are submitted to MDQ, hardware picks all active MDQs using strict priority, and MDQs having the same priority level are chosen using round robin. Each packet will traverse MDQ, TL4 to TL1 levels. Each level contains an array of queues to support scheduling and shaping. As HTB supports classful queuing mechanism by supporting rate and ceil and allow the user to control the absolute bandwidth to particular classes of traffic the same can be achieved by configuring shapers and schedulers on different transmit levels. This series of patches adds support for HTB offload, Patch1: Allow strict priority parameter in HTB offload mode. Patch2: defines APIs such that the driver can dynamically initialize/ deinitialize the send queues. Patch3: Refactors transmit alloc/free calls as preparation for QOS offload code. Patch4: Adds devlink support for the user to configure round-robin priority at TL1 Hariprasad Kelam (2): octeontx2-pf: Refactor schedular queue alloc/free calls octeontx2-pf: Add devlink support to configure TL1 RR_PRIO Naveen Mamindlapalli (2): sch_htb: Allow HTB priority parameter in offload mode octeontx2-pf: Add support for HTB offload Subbaraya Sundeep (1): octeontx2-pf: qos send queues management V2 * ensure other drivers won't effect by allowing 'prio' parameter in htb offload mode. .../ethernet/marvell/octeontx2/af/common.h | 2 +- .../net/ethernet/marvell/octeontx2/af/mbox.h | 9 +- .../net/ethernet/marvell/octeontx2/af/rvu.c | 15 + .../net/ethernet/marvell/octeontx2/af/rvu.h | 1 + .../marvell/octeontx2/af/rvu_debugfs.c | 5 + .../ethernet/marvell/octeontx2/af/rvu_nix.c | 84 +- .../ethernet/marvell/octeontx2/nic/Makefile | 2 +- .../marvell/octeontx2/nic/otx2_common.c | 115 +- .../marvell/octeontx2/nic/otx2_common.h | 30 +- .../marvell/octeontx2/nic/otx2_devlink.c | 84 + .../marvell/octeontx2/nic/otx2_ethtool.c | 31 +- .../ethernet/marvell/octeontx2/nic/otx2_pf.c | 93 +- .../ethernet/marvell/octeontx2/nic/otx2_reg.h | 13 + .../ethernet/marvell/octeontx2/nic/otx2_tc.c | 7 +- .../marvell/octeontx2/nic/otx2_txrx.c | 27 +- .../marvell/octeontx2/nic/otx2_txrx.h | 3 +- .../ethernet/marvell/octeontx2/nic/otx2_vf.c | 8 +- .../net/ethernet/marvell/octeontx2/nic/qos.c | 1547 +++++++++++++++++ .../net/ethernet/marvell/octeontx2/nic/qos.h | 71 + .../ethernet/marvell/octeontx2/nic/qos_sq.c | 304 ++++ .../net/ethernet/mellanox/mlx5/core/en/qos.c | 6 + include/net/pkt_cls.h | 1 + net/sched/sch_htb.c | 7 +- 23 files changed, 2378 insertions(+), 87 deletions(-) create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/qos.c create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/qos.h create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/qos_sq.c --- 2.17.1
