Subject: [PATCH RFC 3/4] vsock/virtio: change the maximum packet size allowed
Date: Thu,  4 Apr 2019 12:58:37 +0200	[thread overview]
Message-ID: <20190404105838.101559-4-sgarzare@redhat.com> (raw)
In-Reply-To: <20190404105838.101559-1-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.
