Subject: [PATCH net 1/2] dpaa2-eth: add irq for the dpmac connect/disconnect event
Date: Thu, 10 Oct 2019 19:19:46 +0300 [thread overview]
Message-ID: <1570724387-5370-2-git-send-email-ioana.ciornei@nxp.com> (raw)
In-Reply-To: <1570724387-5370-1-git-send-email-ioana.ciornei@nxp.com>
From: Florin Chiculita <florinlaurentiu.chiculita@nxp.com>
Add IRQ for the DPNI endpoint change event, resolving the issue
when a dynamically created DPNI gets a randomly generated hw address
when the endpoint is a DPMAC object.
