Re: [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()

This moves passing type of packet from 'info' srtucture to send

Also here replace send with the function name.

function. There is no sense to set type of packet which differs
from type of socket, and since at current time only stream type
is supported, so force to use this type.

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?
