Driver takes significant time to load 1m:20s and unload 40s. Checkpatch script threw warning: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt To eliminate this warning msleep(1) was replaced with msleep(20) before submitting. msleep(20) in init and uninit path for creation and destroying of number of WRBQs, CQs, and EQs is adding to load/unload time. Replace msleep with schedule_timeout_uninterruptible of 1ms as its enough in most cases.
