[PATCH RFC 3/4] vsock/virtio: change the maximum packet size allowed

From: Stefano Garzarella
Date: Thu Apr 04 2019 - 06:59:15 EST


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.
