The dpdk ivshmem build assumes the presence of ivshmem devices as plumbed by
qemu virtual guests.  If you don't have a qemu guest running dpdk won't find any
shared memory devices, which is exactly what you are seeing.  That said, even if
you are running qemu guests, IIRC Fedora doesn't enable ivshmem because the code
has some security and behavioral issues still I think.  You'll need to rebuild
qemu to add support for it.
