[PATCH 0/3] vdpa: Fix SIGSEGV on failed vdpa devices

[Eugenio Pérez]

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.

This is another bersion of the patch proposed in [1], but the subject
didn't match the patch anymore.
