From: Zhu Lingshan
Date: Mon Apr 19 2021 - 02:38:56 EST

This series enabled Intel FGPA SmartNIC C5000X-PL virtio-blk for vDPA.

This series requires:
Stefano's vdpa block patchset: https://lkml.org/lkml/2021/3/15/2113
my patchset to enable Intel FGPA SmartNIC C5000X-PL virtio-net for vDPA:

changes from V3:
remove (pdev->device < 0x1000 || pdev->device > 0x107f) checks in
probe(), because id_table already cut them off(Jason)

changes from V2:
both get_features() and get_config_size() use switch code block

changes from V1:
(1)add comments to explain this driver drives virtio modern devices
and transitional devices in modern mode.(Jason)
(2)remove IFCVF_BLK_SUPPORTED_FEATURES, use hardware feature bits
(3)add error handling and message in get_config_size(Stefano)


Zhu Lingshan (3):
vDPA/ifcvf: deduce VIRTIO device ID when probe
vDPA/ifcvf: enable Intel C5000X-PL virtio-block for vDPA
vDPA/ifcvf: get_config_size should return dev specific config size
