It's just that "Tx zero copy" looks more nature to me (yes, I took the
name from the virtio point of view).
Besides that, naming it to "vhost Rx zero copy" would be a little
weird, based on we have functions like "virtio_dev_rx" in the enqueue
path while here we just touch dequeue path.
OTOH, I seldome say "vhost-user Tx zero copy"; I normally mention it
as "Tx zero copy", without mentioning "vhost-user". For the flag
RTE_VHOST_USER_TX_ZERO_COPY, all vhost-user flags start with "RTE_VHOST_USER_"
prefix.
