Subject: [dpdk-dev] [PATCH v2] net/ring: advertise multi segment TX and scatter RX.
Date: Mon, 28 Sep 2020 20:47:29 +0200	[thread overview]
Message-ID: <1601318849-16691-1-git-send-email-dceara@redhat.com> (raw)
In-Reply-To: <1600425415-31834-1-git-send-email-dceara@redhat.com>

Even though ring interfaces don't support any other TX/RX offloads they
do support sending multi segment packets and this should be advertised
in order to not break applications that use ring interfaces.

Also advertise scatter RX support.
