Subject: [PATCH net-next 4/8] dpaa2-mac: add the MC API for reconfiguring the protocol
Date: Wed, 9 Mar 2022 16:37:47 +0200 [thread overview]
Message-ID: <20220309143751.3362678-5-ioana.ciornei@nxp.com> (raw)
In-Reply-To: <20220309143751.3362678-1-ioana.ciornei@nxp.com>
The MC firmware gained recently a new command which can reconfigure the
running protocol on the underlying MAC. Add this new command which will
be used in the next patches in order to do a major reconfig on the
interface.
