Subject: [PATCH 5/5] crypto: qat - add support for 420xx devices
Date: Fri, 15 Dec 2023 05:01:48 -0500

Add support for 420xx devices by including a new device driver that
supports such devices, updates to the firmware loader and capabilities.

Compared to 4xxx devices, 420xx devices have more acceleration engines
(16 service engines and 1 admin) and support the wireless cipher
algorithms ZUC and Snow 3G.
