From: Akeem G Abodunrin Date: Fri, 1 Apr 2016 10:56:03 +0000 (-0700) Subject: i40e: Move HW flush X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=30728c5bdf2ac6618eebf6949a2e59b3c4cf640f;p=linux-beck.git 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.
