From 5be8308b1614947f056802cb5775307f0ad54ad2 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Thu, 3 Sep 2015 17:19:01 -0400 Subject: [PATCH] i40evf: speed up init 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.
