[PATCH v2 6/8] vsock/virtio: change the maximum packet size allowed

Stefano Garzarella
Fri, 10 May 2019 12:58:41 -0000

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.
