1What: /sys/class/<iface>/queues/rx-<queue>/rps_cpus 2Date: March 2010 3KernelVersion: 2.6.35 4Contact: netdev@vger.kernel.org 5Description: 6 Mask of the CPU(s) currently enabled to participate into the 7 Receive Packet Steering packet processing flow for this 8 network device queue. Possible values depend on the number 9 of available CPU(s) in the system. 10 11What: /sys/class/<iface>/queues/rx-<queue>/rps_flow_cnt 12Date: April 2010 13KernelVersion: 2.6.35 14Contact: netdev@vger.kernel.org 15Description: 16 Number of Receive Packet Steering flows being currently 17 processed by this particular network device receive queue. 18 19What: /sys/class/<iface>/queues/tx-<queue>/tx_timeout 20Date: November 2011 21KernelVersion: 3.3 22Contact: netdev@vger.kernel.org 23Description: 24 Indicates the number of transmit timeout events seen by this 25 network interface transmit queue. 26 27What: /sys/class/<iface>/queues/tx-<queue>/tx_maxrate 28Date: March 2015 29KernelVersion: 4.1 30Contact: netdev@vger.kernel.org 31Description: 32 A Mbps max-rate set for the queue, a value of zero means disabled, 33 default is disabled. 34 35What: /sys/class/<iface>/queues/tx-<queue>/xps_cpus 36Date: November 2010 37KernelVersion: 2.6.38 38Contact: netdev@vger.kernel.org 39Description: 40 Mask of the CPU(s) currently enabled to participate into the 41 Transmit Packet Steering packet processing flow for this 42 network device transmit queue. Possible vaules depend on the 43 number of available CPU(s) in the system. 44 45What: /sys/class/<iface>/queues/tx-<queue>/xps_rxqs 46Date: June 2018 47KernelVersion: 4.18.0 48Contact: netdev@vger.kernel.org 49Description: 50 Mask of the receive queue(s) currently enabled to participate 51 into the Transmit Packet Steering packet processing flow for this 52 network device transmit queue. Possible values depend on the 53 number of available receive queue(s) in the network device. 54 Default is disabled. 55 56What: /sys/class/<iface>/queues/tx-<queue>/byte_queue_limits/hold_time 57Date: November 2011 58KernelVersion: 3.3 59Contact: netdev@vger.kernel.org 60Description: 61 Indicates the hold time in milliseconds to measure the slack 62 of this particular network device transmit queue. 63 Default value is 1000. 64 65What: /sys/class/<iface>/queues/tx-<queue>/byte_queue_limits/inflight 66Date: November 2011 67KernelVersion: 3.3 68Contact: netdev@vger.kernel.org 69Description: 70 Indicates the number of bytes (objects) in flight on this 71 network device transmit queue. 72 73What: /sys/class/<iface>/queues/tx-<queue>/byte_queue_limits/limit 74Date: November 2011 75KernelVersion: 3.3 76Contact: netdev@vger.kernel.org 77Description: 78 Indicates the current limit of bytes allowed to be queued 79 on this network device transmit queue. This value is clamped 80 to be within the bounds defined by limit_max and limit_min. 81 82What: /sys/class/<iface>/queues/tx-<queue>/byte_queue_limits/limit_max 83Date: November 2011 84KernelVersion: 3.3 85Contact: netdev@vger.kernel.org 86Description: 87 Indicates the absolute maximum limit of bytes allowed to be 88 queued on this network device transmit queue. See 89 include/linux/dynamic_queue_limits.h for the default value. 90 91What: /sys/class/<iface>/queues/tx-<queue>/byte_queue_limits/limit_min 92Date: November 2011 93KernelVersion: 3.3 94Contact: netdev@vger.kernel.org 95Description: 96 Indicates the absolute minimum limit of bytes allowed to be 97 queued on this network device transmit queue. Default value is 98 0.
