> Currently there are a couple places where the VF is waiting too long when
> checking the status of registers. This is causing the AVF driver to spin for
> longer than necessary in the __IAVF_STARTUP state. Sometimes it causes
> the AVF to go into the __IAVF_COMM_FAILED, which may retrigger the
> __IAVF_STARTUP state. Try to reduce the chance of this happening by
> removing unnecessary wait times in VF bringup/resets.
