I understand, could we use another solution ? Like a memif interface
in DPDK and libmemif in Linux?
The issue is accessing kernel networking devices. Both virtio user
and XDP are faster for that. Memif is for doing process to process networking.
For dpdk <-> kernel, as you are mentioning virtio-user/vhost, let me
add that there is some activity on this side, with VDUSE.
Maxime is working on the VDUSE kernel and dpdk bits.
He gave a talk about the current status during the summit and some
performance numbers:

Thanks for sharing David.
I'd like just to add some more information on VDUSE if you want to
experiment with VDUSE, which is still under development:
