This series allows userspace to query device features of
a vDPA device through a new netlink attr
VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES

This series also make some fields of virtio-net
device config space conditional on the feature bits,
this means:

MTU should be conditional on VIRTIO_F_NET_MTU
MAC should be conditional on VIRTIO_F_NET_MAC
MQ should be conditional on VIRTIO_F_NET_MQ

For details, please refer to commit message
of patch 2/2

Thanks!
