Hi,
This patchset introduces some updates to mlx5 next shared branch.
1) Eli Cohen, Adds HW and mlx5_core driver definitions and bits for
upcoming mlx5 VDPA driver support.
2) Michael Guralnik Enables count actions for simple allow steering
rule.
In case of no objections this patchset will be applied to mlx5-next and
later sent to rdma and net-next trees.
Thanks,
Saeed.

From: Eli Cohen <eli@mellanox.com>
mlx5_fill_page_frag_array() is used to populate dma addresses to
resources that require it, such as QPs, RQs etc. When the resource is
used, PA list permissions are ignored. For resources that use MTT list,
the user is required to provide the access rights. Subsequent patches
use resources that require MTT lists, so modify API and implementation
to support that.

VDPA is a new interface that will be added in subsequent patches. It
uses mlx5 core devices and resources. Add an interface type for it.

Rename mlx5_ifc_device_virtio_emulation_cap_bits to
mlx5_ifc_virtio_emulation_cap_bits to match names produced by the
tools producing these auto generated files.
In addition missing capabilities that will be required by VDPA
implementation.
