Subject: [dpdk-dev] [PATCH 12/40] net/virtio: remove bus type enum
Date: Sun, 20 Dec 2020 22:13:37 +0100 [thread overview]
Message-ID: <20201220211405.313012-13-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20201220211405.313012-1-maxime.coquelin@redhat.com>
Bus type awareness at the generic ethdev level is no
more needed as previous patches have made it bus-agnostic.
This patch removes it from struct virtio_hw.
