ADQ provides traffic isolation for application flows in hardware and ability to steer traffic to a given traffic class. This helps in aligning NIC queues to application threads. Traffic classes are configured using mqprio framework of tc command and mapped to HW channels(VSIs) in the driver. The queue set of each traffic class is managed by corresponding VSI. Each traffic channel can be configured with bandwidth rate-limiting limits and is offloaded to the hardware through the mqprio framework by specifying the mode option as 'channel' and shaper option as 'bw_rlimit'. Next, the flows of application can be steered into a given traffic class using "tc filter" command. The option "skip_sw hw_tc x" indicates hw-offload of filtering and steering filtered traffic into specified TC. Non-matching traffic flows through TC0. When channel configuration are removed queue configuration is set to default and filters configured on individual traffic classes are deleted. example: $ ethtool -K eth0 hw-tc-offload on Configure 3 traffic classes and map priority 0,1,2 to TC0, TC1 and TC2 respectively. TC0 has 2 queues from offset 0 & TC1 has 8 queues from offset 2 and TC2 has 4 queues from offset 10. Enable hardware offload of channels. $ tc qdisc add dev eth0 root mqprio num_tc 3 map 0 1 2 queues \ 2@0 8@2 4@10 hw 1 mode channel $ tc qdisc show dev eth0 qdisc mqprio 8001: root tc 2 map 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 0 queues:(0:1) (2:9) (10:13) mode:channel Configure two filters to match based on dst ipaddr, dst tcp port and redirect to TC1 and TC2. $ tc qdisc add dev eth0 clsact $ tc filter add dev eth0 protocol ip ingress prio 1 flower\ dst_ip 192.168.1.1/32 ip_proto tcp dst_port 80\ skip_sw hw_tc 1 $ tc filter add dev eth0 protocol ip ingress prio 1 flower\ dst_ip 192.168.1.1/32 ip_proto tcp dst_port 5001\ skip_sw hw_tc 2 $ tc filter show dev eth0 ingress Delete traffic classes configuration: $ sudo tc qdisc del dev eth0 root --- The following are changes since commit 2641b62d2fab52648e34cdc6994b2eacde2d27c1: phy: micrel: ksz8041nl: do not use power down mode and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE Kiran Patil (3): ice: Add infrastructure for mqprio support via ndo_setup_tc ice: enable ndo_setup_tc support for mqprio_qdisc ice: Add tc-flower filter support for channel drivers/net/ethernet/intel/ice/ice.h | 108 +- drivers/net/ethernet/intel/ice/ice_base.c | 34 +- drivers/net/ethernet/intel/ice/ice_dcb_lib.c | 201 ++-- drivers/net/ethernet/intel/ice/ice_dcb_lib.h | 10 +- drivers/net/ethernet/intel/ice/ice_eswitch.c | 2 +- drivers/net/ethernet/intel/ice/ice_ethtool.c | 10 + drivers/net/ethernet/intel/ice/ice_lib.c | 384 ++++++- drivers/net/ethernet/intel/ice/ice_lib.h | 12 +- drivers/net/ethernet/intel/ice/ice_main.c | 970 +++++++++++++++++- drivers/net/ethernet/intel/ice/ice_sched.c | 68 +- drivers/net/ethernet/intel/ice/ice_sched.h | 2 + drivers/net/ethernet/intel/ice/ice_switch.c | 119 +++ drivers/net/ethernet/intel/ice/ice_switch.h | 2 + drivers/net/ethernet/intel/ice/ice_tc_lib.c | 217 +++- drivers/net/ethernet/intel/ice/ice_tc_lib.h | 22 + drivers/net/ethernet/intel/ice/ice_txrx.h | 7 + drivers/net/ethernet/intel/ice/ice_type.h | 3 + .../net/ethernet/intel/ice/ice_virtchnl_pf.c | 4 +- 18 files changed, 2021 insertions(+), 154 deletions(-) -- 2.31.1
