[ovs-dev] [PATCH v1] Docs: Remove zero-copy QEMU limitation.

[Loftus, Ciara]

> 
> Remove note regarding zero-copy compatibility with QEMU >= 2.7.
> 
> When zero-copy was introduced to OVS it was incompatible with QEMU >=
> 2.7. This issue has since been fixed in DPDK with commit
> 803aeecef123 ("vhost: fix dequeue zero copy with virtio1") and
> backported to DPDK LTS branches. Remove the reference to this
> issue in the zero-copy documentation.
