Subject: [PATCH net-next 3/8] dpaa2-mac: add the MC API for retrieving the version
Date: Wed, 9 Mar 2022 16:37:46 +0200 [thread overview]
Message-ID: <20220309143751.3362678-4-ioana.ciornei@nxp.com> (raw)
In-Reply-To: <20220309143751.3362678-1-ioana.ciornei@nxp.com>
The dpmac_get_api_version command will be used in the next patches to
determine if the current firmware is capable or not to change the
Ethernet protocol running on the MAC.
