These statistics can help to estimate efficiency of
Work Requests batching and show busy/idle polls ratio.
Send: the doorbell updates statistics for verbs
provider are incremented per each ibv_post_send call,
for mlx5_dv per each ibv_wr_complete call.
Recv: the doorbell updates statistics for both
providers are updated when either ibv_post_recv
or ibv_post_srq_recv functions are called.
Each qpair on initialization accepts an optional
pointer to shared statistics (nvmf/nvme poll groups).
If the pointer to statistics is not provided then
qpair allocates its own structure. That is done
to support cases when NVME RDMA initiator doesn't
use poll groups, so we can avoid checks that qpair
has statistics in IO path

With min supported DPDK >= 19.11 there is no need
to check that the buffer can be split over
several Memory Regions so we can remove this check.
Keep assert that translation length is not less than
request as a sanity check.

Next patches will add usage of new functions in

Verbs implementation: doesn't differ from the original:
- send_wr: saves WRs in the qpair internal structure
- flush_wr: calls ibv_post_send
Direct Verbs implementation:
- send_wr: calls ibv_wr_start for the first WR;
Calls opcode-specific function to add a WQE to SQ
Tracks queued WRs to return a correct pointer to 'bad_wr'
- flush_wr: calls ibv_wr_complete - it flushes to the NIC
all WRs added between ibv_wr_start and ibv_wr_complete

RDMA provider is used as an abstraction layer and allows
to add vendor specific verbs implementation. This patch adds
an interface to create and destroy qpairs and its implementation
using regular verbs API.
Future patches will add functions to queue/flush Work Requests,
enable usage of RDMA providers API in NVMEoF target/initiator and
add Mellanox Direct Verbs implementation. This abstraction layer
is flexible enough to add other vendor's implementations.
The choice of a specific RDMA provider will be made at
the configuration step, it doesn't add any runtime overhead.
