That would break 32 bit build. please also do more build and function
test, with and without CONFIG_RTE_VIRTIO_VDEV enabled, to make sure
we will not break anything. I'm sure you will meet build error without
that option enabled.
BTW, let's be consistent with using VIRTIO_USER_DEV instead of VDEV
or VIRTIO_VDEV?
Another thing that might be a bit late to ask is that how about
removing the vhost-net support? I mean, it's DPDK; if user stick
to using DPDK virtio-user, he will stick to using DPDK vhost-user
as well, but not the vhost-net. So, let's keep it being simple
first. And if there is really a need for vhost-net, we can add it
back later, easily. Makes sense?
I also would suggest you do a rebase based on my latest tree.
