RDMA/ocrdma: Query and initalize the PFC SL
This patch implements routine to query the PFC priority from the adapter port.
Following are the changes implemented:
* A new FW command is implemented to query the operational/admin
DCBX configuration from the FW and obtain active priority(service level).
* Adds support for the async event reported by FW when the PFC priority
changes. Service level is re-initialized during modify_qp or
create_ah, based on this event.
* Maintain SL value in ocrdma_dev structure and refer that as and
when needed.
be2net driver sends shutdown event to ocrdma during shutdown/reboot.
As part of event processing, ocrdma calls close() and remove() to
free all the resources associated with ocrdma. This also frees
irqs used by ocrdma

Commit c1be5232d21d "Fix micro UAR allocator" broke binary compatibility
between libmlx5 and mlx5_ib since it defines a different value to the number of
micro UARs per page, leading to wrong calculation in libmlx5. This patch
defines struct mlx5_ib_alloc_ucontext_req_v2 as an extension to struct
mlx5_ib_alloc_ucontext_req. The extended size is determined in
mlx5_ib_alloc_ucontext() and in case of old library we use uuarn 0 which works
fine -- this is acheived due to create_user_qp() falling back from high to
medium then to low class where low class will return 0. For new libraries we
use the more sophisticated allocation algorithm.

mlx4_core: Roll back round robin bitmap allocation commit for CQs, SRQs, and MPTs
Commit f4ec9e9 "mlx4_core: Change bitmap allocator to work in round-robin fashion"
introduced round-robin allocation (via bitmap) for all resources which allocate
via a bitmap.
Round robin allocation is desirable for mcgs, counters, pd's, UARs, and xrcds.
These are simply numbers, with no involvement of ICM memory mapping.
Round robin is required for QPs, since we had a problem with immediate
reuse of a 24-bit QP number (commit f4ec9e9).
However, for other resources which use the bitmap allocator and involve
mapping ICM memory -- MPTs, CQs, SRQs -- round-robin is not desirable.
What happens in these cases is the following:
ICM memory is allocated and mapped in chunks of 256K.
Since the resource allocation index goes up monotonically, the allocator
will eventually require mapping a new chunk. Now, chunks are also unmapped
when their reference count goes back to zero. Thus, if a single app is
running and starts/exits frequently we will have the following situation:
When the app starts, a new chunk must be allocated and mapped.
When the app exits, the chunk reference count goes back to zero, and the
chunk is unmapped and freed. Therefore, the app must pay the cost of allocation
and mapping of ICM memory each time it runs (although the price is paid only when
allocating the initial entry in the new chunk).
For apps which allocate MPTs/SRQs/CQs and which operate as described above,
this presented a performance problem.
We therefore roll back the round-robin allocator modification for MPTs, CQs, SRQs.
