From 30728c5bdf2ac6618eebf6949a2e59b3c4cf640f Mon Sep 17 00:00:00 2001 From: Akeem G Abodunrin Date: Fri, 1 Apr 2016 03:56:03 -0700 Subject: [PATCH] i40e: Move HW flush This patch moves the HW flush routine to the end of the reset flow, after the completion of writing to the device VFLR registers- the benefit is to avoid problems in the passthrough routines.
