Subject: [PATCH v2 7/8] vsock/virtio: increase RX buffer size to 64 KiB
Date: Fri, 10 May 2019 14:58:42 +0200	[thread overview]
Message-ID: <20190510125843.95587-8-sgarzare@redhat.com> (raw)
In-Reply-To: <20190510125843.95587-1-sgarzare@redhat.com>

In order to increase host -> guest throughput with large packets,
we can use 64 KiB RX buffers.
