idpf: add support for SW triggered interrupts

Browse source

[ Upstream commit 93433c1d91 ]

SW triggered interrupts are guaranteed to fire after their timer
expires, unlike Tx and Rx interrupts which will only fire after the
timer expires _and_ a descriptor write back is available to be processed
by the driver.

Add the necessary fields, defines, and initializations to enable a SW
triggered interrupt in the vector's dyn_ctl register.
