Subject[PATCH v6 0/4] Show statistics for a vdpa device
Date
The following four patch series adds support to read vendor statistics
for a vdpa device.

The first patch is just a cleanup fix.
The second patch lays the ground to allow an upstream driver to provide
statistics in the form of an attribute name/attribute value pairs.

The makes changes to locking scheme to use readers/writers semaphore
instead if mutex.

The forth patch implements this for mlx5_vdpa which gives received
descriptors and completed descriptors information for all the
virtqueues.

v5 -> v6:
1. Move negotiated features insertion from mlx5 into vdpa core.
2. Include the patch that changes the lock in this series.


Eli Cohen (4):
vdpa: Fix error logic in vdpa_nl_cmd_dev_get_doit
vdpa: Add support for querying vendor statistics
net/vdpa: Use readers/writers semaphore instead of mutex
vdpa/mlx5: Add support for reading descriptor statistics
