Subject: [net-next 03/14] i40e: Move HW flush
Date: Wed, 6 Apr 2016 20:29:28 -0700 [thread overview]
Message-ID: <1459999779-22254-4-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1459999779-22254-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Akeem G Abodunrin <akeem.g.abodunrin@intel.com>
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.
