SubjectRe: [RFC PATCH v5 09/19] virtio/vsock: set packet's type in send
The title is a little cryptic, maybe a something like:

virtio/vsock: set packet's type in virtio_transport_send_pkt_info()

Also here replace send with the function name.

I'm not a native speaker, but I would rephrase a bit the commit message:

There is no need to set type of packet which differs from type of
socket. Since at current time only stream type is supported, set
it directly in virtio_transport_send_pkt_info(), so callers don't
need to set it.

If I haven't missed something, we can remove 'type' parameter also from
virtio_transport_send_credit_update(), right?
