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.
