[dpdk-dev] [RFC PATCH 00/11] net/virtio: packed ring layout

[Jens Freimann]

Hi Yuanhan,

I rebased your patches on next-virtio/for-testing to current master,
made sure every patch compiles and still works. 
I'm implementing the receive path now to eventually get some benchmark
results for that as well (Patches not included yet)

Any comments to the existing patches are welcome, I will change them accordingly.

regards,
Jens
