Subject: [net-next 02/15] igb: read PBA number from flash
Date: Mon, 28 Sep 2020 10:58:55 -0700	[thread overview]
Message-ID: <20200928175908.318502-3-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20200928175908.318502-1-anthony.l.nguyen@intel.com>

From: Gal Hammer <ghammer@redhat.com>

Fixed flash presence check for 82576 controllers so the part
number string is read and displayed correctly.
