From: Leon Romanovsky <leonro@xxxxxxxxxxxx>
Changelog:
v0 -> v1:
* Changed wording of counter comment
* Removed unneeded assignments
* Added extra patch to present global counters
* I didn't change QP type from int to be enum ib_qp_type,
because it caused to cyclic dependency between ib_verbs.h and
rdma_counter.h.

Hi,
This series from Mark provides dynamic statistics infrastructure.
He uses netlink interface to configure and retrieve those counters.
This infrastructure allows to users monitor various objects by binding
to them counters. As the beginning, we used QP object as target for
those counters, but future patches will include ODP MR information too.
Two binding modes are supported:
- Auto: This allows a user to build automatic set of objects to a counter
according to common criteria. For example in a per-type scheme, where in
one process all QPs with same QP type are bound automatically to a single
counter.
- Manual: This allows a user to manually bind objects on a counter.
Those two modes are mutual-exclusive with separation between processes,
objects created by different processes cannot be bound to a same counter.
For objects which don't support counter binding, we will return
pre-allocated counters.
$ rdma statistic qp set link mlx5_2/1 auto type on
$ rdma statistic qp set link mlx5_2/1 auto off
$ rdma statistic qp bind link mlx5_2/1 lqpn 178
$ rdma statistic qp unbind link mlx5_2/1 cntn 4 lqpn 178
$ rdma statistic show
$ rdma statistic qp mode
Thanks
