NEC released a PMD and a Linux driver for virtual machines.
It is based on memory copy.
It is available at:
http://dpdk.org/browse/memnic
The shared memory must be created first in the host.
Then it can be configured as a virtual device in QEMU thanks to ivshmem.
This new virtual NIC will be usable into a DPDK application or with any Linux
distribution which can load memnic.ko.
Using this API, there can be various implementations on the host side:
- OVDK has native mapping of that memory
- memnic-host-sim (will be provided soon)
- DPDK PMD (to be done)
- etc...
The PMD driver can be dynamically loaded:
testpmd [..] -d librte_pmd_memnic_copy.so [..]
For non-DPDK application, the Linux kernel driver can be loaded:
insmod memnic.ko
More information and documentation are available into:

http://dpdk.org/doc/memnic-pmd (HTML version)
Thanks to NEC. Enjoy
