In linux kernel since version 2.6.20 (release Date: 2007-02-04)
The Cyclades-Z family of multiport cards allows 2 (two) driver op
modes: polling and interrupt. In polling mode, the driver will check
the status of the Cyclades-Z ports every certain amount of time
(which is called polling cycle and is configurable). In interrupt
mode, it will use an interrupt line (IRQ) in order to check the
status of the Cyclades-Z ports. The default op mode is polling. If
unsure, say N.
