Qemu falls back on userland handlers even if vhost-user and vhost-vdpa cases. These assumes a tap device can handle the packets.
If a vdpa device fail to start, it can trigger a sigsegv because of that. Add dummy receivers that return no progress so it can keep running. Tested with a modified version of vp_vdpa to fail negotiation. v2: * Replace dummy receive_{iov,raw} with receive callback. * Delete fix indentation commit, we don't touch that code anymore.
