According to the NetworkingTodo page on the KVM wiki, zero-copy RX
for macvtap is in fact on the roadmap, assigned to Xin:

AFAIK Xin left Intel and is not working on it.
Contributions are welcome.

The Release Notes for RHEL 6.2 (originally published on 12/06/2011)
also specifically mention macvtap/vhost zero-copy capabilities as
being included as a Technology Preview:

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.2_Release_Notes/virtualization.html

Since I've been unable to find much information on the current
status of this development, can anyone confirm if this functionality
is still in the works? If so, is there any planned ETA?

Thanks,
Robert Vineyard

I think this means TX.
