Subject: [PATCH 3/8] igb: Use FIELD_GET() to extract Link Width
Date: Mon, 11 Sep 2023 15:14:56 +0300 [thread overview]
Message-ID: <20230911121501.21910-4-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20230911121501.21910-1-ilpo.jarvinen@linux.intel.com>
Use FIELD_GET() to extract PCIe Negotiated Link Width field instead of
custom masking and shifting.
