> 
> Shorten up the delays in the init task, allowing the VF driver to initialize
> faster. This aids performance in load/unload tests and mitigates DMAR errors
> in VF enable/disable tests with absurdly short delays. In the real world, the
> VF driver will come up more quickly.
> 
> The original values were set conservatively based on what we expected from
> the firmware in terms of performance. Now that the driver is in use and we
> know how well firmware responds to our requests, we can shorten these
> delays.
