During Kdump aacraid controller IOP reset is invoked, IOP reset takes approx 40 seconds to bring the controller back up and running. with timeout of 120 seconds and anything more than 2 controllers will cause kdump to timeout. This patchset implements a new reset mechanism called DropIO, that induces the fw to drop any pending IO in the fw and making the reset process quicker.
