Subject: [PATCH net-next v5 5/5] vsock/virtio: change the maximum packet size allowed
Date: Tue, 30 Jul 2019 17:43:34 +0200	[thread overview]
Message-ID: <20190730154334.237789-6-sgarzare@redhat.com> (raw)
In-Reply-To: <20190730154334.237789-1-sgarzare@redhat.com>

Since now we are able to split packets, we can avoid limiting
their sizes to VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE.
Instead, we can use VIRTIO_VSOCK_MAX_PKT_BUF_SIZE as the max
packet size.
