RDMA/mlx5: Extend ODP statistics with operation count
The current ODP counters represent the total number of pages
handled, but it is not enough to understand the effectiveness
of these operations.
Extend the ODP counters to include the number of times page fault
and invalidation events were handled.
Example for a single page fault handling 512 pages:
- page_fault: incremented by 512 (total pages)
- page_fault_handled: incremented by 1 (operation count)
The same example is applicable for page invalidation too.
Previous output:
$ rdma stat mr
dev rocep8s0f0 mrn 8 page_faults 27 page_invalidations 0 page_prefetch 29
New output:
$ rdma stat mr
dev rocep8s0f0 mrn 21 page_faults 512 page_faults_handled 1
page_invalidations 0 page_invalidations_handled 0 page_prefetch 51200
