+What: /sys/class/<iface>/queues/rx-<queue>/rps_cpus
+Date: March 2010
+KernelVersion: 2.6.35
+Contact: netdev@vger.kernel.org
+Description:
+ Mask of the CPU(s) currently enabled to participate into the
+ Receive Packet Steering packet processing flow for this
+ network device queue. Possible values depend on the number
+ of available CPU(s) in the system.

+What: /sys/class/<iface>/queues/tx-<queue>/tx_timeout
+Date: November 2011
+KernelVersion: 3.3
+Contact: netdev@vger.kernel.org
+Description:
+ Indicates the number of transmit timeout events seen by this
+ network interface transmit queue.
+
+What: /sys/class/<iface>/queues/tx-<queue>/tx_maxrate
+Date: March 2015
