[PATCH V2 0/3] vDPA/ifcvf: enables Intel C5000X-PL virtio-blk

[Zhu Lingshan]

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:
https://lkml.org/lkml/2021/3/17/432

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
directly(Jason)
(3)add error handling and message in get_config_size(Stefano)

Thanks!

[PATCH V2 1/3] vDPA/ifcvf: deduce VIRTIO device ID when probe

[Zhu Lingshan]

This commit deduces VIRTIO device ID as device type when probe,
then ifcvf_vdpa_get_device_id() can simply return the ID.
ifcvf_vdpa_get_features() and ifcvf_vdpa_get_config_size()
can work properly based on the device ID.

Should we put a warning here too otherwise feature could be seen 
unassigned?

I slightly prefer the switch, but I don't have a strong opinion.

However, if we want to use if/else, we should follow 
`Documentation/process/coding-style.rst` line 166:
     Note that the closing brace is empty on a line of its own, **except** in
     the cases where it is followed by a continuation of the same statement,
     ie a ``while`` in a do-statement or an ``else`` in an if-statement, like

also `scripts/checkpatch.pl --strict` complains:

     CHECK: braces {} should be used on all arms of this statement
     #209: FILE: drivers/vdpa/ifcvf/ifcvf_main.c:355:
     +	if (vf->dev_type == VIRTIO_ID_NET)
     [...]
     +	else if (vf->dev_type == VIRTIO_ID_BLOCK)
     [...]
     +	else {
     [...]

     CHECK: Unbalanced braces around else statement
     #215: FILE: drivers/vdpa/ifcvf/ifcvf_main.c:361:
     +	else {

Stefano

Thanks Stefano, the reason is we only have one line code after if, so 
looks like {} is unnecessary, I agree switch can clear up
code style confusions. I will add this in v3.

Thanks!
