Dno_hz.rst114 and such CPUs are said to be "adaptive-ticks CPUs". This is important
124 By default, no CPU will be an adaptive-ticks CPU. The "nohz_full="
125 boot parameter specifies the adaptive-ticks CPUs. For example,
126 "nohz_full=1,6-8" says that CPUs 1, 6, 7, and 8 are to be adaptive-ticks

Dcxgb.txt30 Adaptive Interrupts (adaptive-rx)
33 This feature provides an adaptive algorithm that adjusts the interrupt
41 By default, adaptive-rx is disabled.
42 To enable adaptive-rx:
44 ethtool -C <interface> adaptive-rx on
46 To disable adaptive-rx, use ethtool:
48 ethtool -C <interface> adaptive-rx off
50 After disabling adaptive-rx, the timer latency value will be set to 50us.
51 You may set the timer latency after disabling adaptive-rx:
