Subject: [PATCH RFC 4/4] vsock/virtio: increase RX buffer size to 64 KiB
Date: Thu,  4 Apr 2019 12:58:38 +0200	[thread overview]
Message-ID: <20190404105838.101559-5-sgarzare@redhat.com> (raw)
In-Reply-To: <20190404105838.101559-1-sgarzare@redhat.com>

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