Subject: [PATCH 18/20] dpaa_eth: extend delays in ndo_stop
Date: Tue, 8 Oct 2019 15:10:39 +0300 [thread overview]
Message-ID: <1570536641-25104-19-git-send-email-madalin.bucur@nxp.com> (raw)
In-Reply-To: <1570536641-25104-1-git-send-email-madalin.bucur@nxp.com>
Make sure all the frames that are in flight have time to be processed
before the interface is completely brought down. Add a missing delay
for the Rx path.
