This series allows userspace to query device config space of vDPA
devices and the management devices through netlink,

This series has introduced a new netlink attr
VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES, this should be used to query
features of vDPA devices than the management device.
Please help review.
I can't merge this for this merge window.
Am I right when I say that the new thing here is patch 5/6 + new
comments?
If yes I can queue it out of the window, on top.
So at this point, can you please send patches on top of the vhost
tree? I think these are just patches 3 and 5 but please confirm.
I will rebase them on vhost tree and resend them soon, main changes are
in patch 5,
we have made MTU, MAC, MQ conditional there. And there are some new
comments as
you suggested.
Thanks,
Zhu Lingshan
Thanks!

cap size(Jason)
(3) Introduced a new attr VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES
(4) Show the changes of iproute2 output before and after 5/6 patch(Jason)
(5) Fix cast warning in vdpa_fill_stats_rec()
Zhu Lingshan (6):
vDPA/ifcvf: get_config_size should return a value no greater than dev
implementation
vDPA/ifcvf: support userspace to query features and MQ of a management
device
vDPA: allow userspace to query features of a vDPA device
vDPA: !FEATURES_OK should not block querying device config space
vDPA: Conditionally read fields in virtio-net dev config space
fix 'cast to restricted le16' warnings in vdpa.c
