So this one is really annoying to configure.

First it asks for vDPA driver for virtio devices (VIRTIO_VDPA) support.

If you say 'n', it then asks *again* for VDPA drivers (VDPA_MENU).

And then when you say 'n' to *that* it asks you for Vhost driver for
vDPA-based backend (VHOST_VDPA).

This kind of crazy needs to stop.

Doing kernel configuration is not supposed to be like some truly
horrendously boring Colossal Cave Adventure game where you have to
search for a way out of maze of twisty little passages, all alike.
