[PATCH v2 0/5] vDPA driver for Alibaba ENI

[Wu Zongyong]

This series implements the vDPA driver for Alibaba ENI(Elastic Network
Interface) which is build based on virtio-pci 0.9.5 specification.

A new vdpa attribute VDPA_ATTR_DEV_F_VERSION_1 is introduced to guide
users to choose right virtqueue size if the vdpa device is legacy.

Change From V1:
- add new vdpa attribute VDPA_ATTR_DEV_F_VERSION_1 to indicate whether
  the vdpa device is legacy
- implement dedicated driver for Alibaba ENI instead a legacy virtio-pci
  driver as suggested by Jason Wang
- some bugs fixed

Wu Zongyong (5):
  virtio-pci: introduce legacy device module
  vdpa: fix typo
  vp_vdpa: add vq irq offloading support
  vdpa: add new vdpa attribute VDPA_ATTR_DEV_F_VERSION_1
  eni_vdpa: add vDPA driver for Alibaba ENI
