This series implements the vDPA driver for Alibaba ENI(Elastic Network
Interface) which is build based on virtio-pci 0.9.5 specification.
Changes since V2:
- add new attribute VDPA_ATTR_DEV_MIN_VQ_SIZE instead
VDPA_ATTR_DEV_F_VERSION_1 to guide users to choose correct virtqueue
size as suggested by Jason Wang
- present ACCESS_PLATFORM in get_features callback as suggested by Jason
Wang
- disable this driver on Big Endian host as suggested by Jason Wang
- fix a typo
Changes since 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
