[Qemu-devel] [PULL 05/25] vhost-net: move stubs to a separate file |
Date: |

From: Paolo Bonzini <address@hidden>
There is no reason for CONFIG_VHOST_NET to be specific to a single target;
it is a host feature that can be add to all targets, as long as they support
the virtio-net device. Currently CONFIG_VHOST_NET depends on CONFIG_KVM,
but ioeventfd support is present in the core memory API and works with
other accelerators as well.
As a first step, move the vhost-net stubs to a separate file. Later, they
will become conditional on CONFIG_VIRTIO_NET, which is not available in .c
files.
