Message-ID: <1429844592.20211229205044@nowatel.com> Date: Wed, 29 Dec 2021 20:50:44 +0100 From: Stanisław Czech <s.czech@...atel.com> To: "netdev@...r.kernel.org" <netdev@...r.kernel.org> CC: Maxim Mikityanskiy <maximmi@...lanox.com> Subject: htb offload support in i40e (intel nic) Hi, I saw that the htb offload needs additional changes in the mlx5 driver to support it. I couldn't find any info regarding the htb offload support on any other drivers/vendors like intel nic (i40e) We use multiple XL710 that seems to support hardware tc queues: qdisc noqueue 0: dev lo root refcnt 2 qdisc mq 0: dev enp65s0f1 root qdisc fq_codel 0: dev enp65s0f1 parent :18 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :17 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :16 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :15 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :14 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :13 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :12 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :11 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :10 limit 10240p flows 1024 quantum 1514 target 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :f limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :e limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :d limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :c limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :b limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :a limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :9 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :8 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :7 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :6 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :5 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :4 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :3 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :2 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 qdisc fq_codel 0: dev enp65s0f1 parent :1 limit 10240p flows 1024 quantum 1514 t arget 5ms interval 100ms memory_limit 32Mb ecn drop_batch 64 Is this enough to support the htb offload or we must wait for the driver update to support it?
