When multiple traffic flows reach transmit level with the same priority, with Round Robin scheduling traffic flow with the highest quantum value is picked. With this support, the user can add multiple classes with the same priority and different quantum in htb offload. This series of patches adds support for the same. Patch1: implement transmit schedular allocation algorithm as preparation for support round robin scheduling. Patch2: Allow quantum parameter in HTB offload mode. Patch3: extends octeontx2 htb offload support for Round Robin scheduling Naveen Mamindlapalli (3): octeontx2-pf: implement transmit schedular allocation algorithm sch_htb: Allow HTB quantum parameter in offload mode octeontx2-pf: htb offload support for Round Robin scheduling .../marvell/octeontx2/nic/otx2_common.c | 1 + .../marvell/octeontx2/nic/otx2_common.h | 1 + .../net/ethernet/marvell/octeontx2/nic/qos.c | 347 ++++++++++++++++-- .../net/ethernet/marvell/octeontx2/nic/qos.h | 11 +- .../net/ethernet/mellanox/mlx5/core/en/qos.c | 4 +- include/net/pkt_cls.h | 1 + net/sched/sch_htb.c | 7 +- 7 files changed, 329 insertions(+), 43 deletions(-) --- 2.17.1
