There is no reason for drivers to do this, the core code should take of
everything. The drivers will provide their information from rodata to
describe their modifications to the core's base uapi specification.
The core uses this to build up the runtime uapi for each device.

Now that the unregister_netdev flow for IPoIB no longer relies on external
code we can now introduce the use of priv_destructor and
needs_free_netdev.
The rdma_netdev flow is switched to use the netdev common priv_destructor
instead of the special free_rdma_netdev and the IPOIB ULP adjusted:
- priv_destructor needs to switch to point to the ULP's destructor
which will then call the rdma_ndev's in the right order
- We need to be careful around the error unwind of register_netdev
as it sometimes calls priv_destructor on failure
- ULPs need to use ndo_init/uninit to ensure proper ordering
of failures around register_netdev
Switching to priv_destructor is a necessary pre-requisite to using
the rtnl new_link mechanism.
The VNIC user for rdma_netdev should also be revised, but that is left for
another patch.

the RDMA WRITE and SEND_INV WR chain submitted by the NVME-oF target

This reduces uP overhead per NVME-oF IO, and results in over 10%

In c4iw_create_qp() there are several struct members which potentially
aren't inintialized like uresp.rq_key. I've fixed this code before in
in commit ae1fe07f3f42 ("RDMA/cxgb4: Fix stack info leak in
c4iw_create_qp()") so this time I'm just going to take a big hammer
approach and memset the whole struct to zero. Hopefully, it will stay
fixed this time.
In c4iw_create_srq() we don't clear uresp.reserved.

This does the same as the patch before, except for ioctl. The rules are
the same, but for the ioctl methods the core code handles setting up the
uobject.
- Retrieve the ib_dev from the uobject->context->device. This is
safe under ioctl as the core has already done rdma_alloc_begin_uobject
and so CREATE calls are entirely protected by the rwsem.
- Retrieve the ib_dev from uobject->object
- Call ib_uverbs_get_ucontext()

In the current implementation, the driver tries to allocate contiguous
memory, and if it fails, it falls back to 4K fragmented allocation.
Once the memory is fragmented, the first allocation might take a lot
of time, and even fail, which can cause connection failures.
This patch changes the logic to always allocate with 4K granularity,
since it's more robust and more likely to succeed.
This patch was tested with Lustre and no performance degradation
was observed.
Note: This commit eliminates the "shrinking WQE" feature. This feature
depended on using vmap to create a virtually contiguous send WQ.
vmap use was abandoned due to problems with several processors (see the
commit cited below). As a result, shrinking WQE was available only with
physically contiguous send WQs. Allocating such send WQs caused the
problems described above.
Therefore, as a side effect of eliminating the use of large physically
contiguous send WQs, the shrinking WQE feature became unavailable.

This clearly indicates that the input is a bitwise combination of values
in an enum, and identifies which enum contains the definition of the bits.
Special accessors are provided that handle the mandatory validation of the
allowed bits and enforce the correct type for bitwise flags.
If we had introduced this at the start then the kabi would have uniformly
used u64 data to pass flags, however today there is a mixture of u64 and
u32 flags. All places are converted to accept both sizes and the accessor
fixes it. This allows all existing flags to grow to u64 in future without
any hassle.
Finally all flags are, by definition, optional. If flags are not passed
the accessor does not fail, but provides a value of zero.

Since neither ib_post_send() nor ib_post_recv() modify the data structure
their second argument points at, declare that argument const. This change
makes it necessary to declare the 'bad_wr' argument const too and also to
modify all ULPs that call ib_post_send(), ib_post_recv() or
ib_post_srq_recv(). This patch does not change any functionality but makes
it possible for the compiler to verify whether the
ib_post_(send|recv|srq_recv) really do not modify the posted work request.
To make this possible, only one cast had to be introduce that casts away
constness, namely in rpcrdma_post_recvs(). The only way I can think of to
avoid that cast is to introduce an additional loop in that function or to
change the data type of bad_wr from struct ib_recv_wr ** into int
(an index that refers to an element in the work request list). However,
both approaches would require even more extensive changes than this
patch.

When a CX5 device is configured in dual-port RoCE mode, after creating
many VFs against port 1, creating the same number of VFs against port 2
will flood kernel/syslog with something like
"mlx5_*:mlx5_ib_bind_slave_port:4266:(pid 5269): port 2 already
affiliated."
So basically, when traversing mlx5_ib_dev_list, mlx5_ib_add_slave_port()
repeatedly attempts to bind the new mpi structure to every device on the
list until it finds an unbound device.
Change the log level from warn to dbg to avoid log flooding as the warning
should be harmless.

We have a parallel unlocked reader and writer with ib_uverbs_get_context()
vs everything else, and nothing guarantees this works properly.
Audit and fix all of the places that access ucontext to use one of the
following locking schemes:
- Call ib_uverbs_get_ucontext() under SRCU and check for failure
- Access the ucontext through an struct ib_uobject context member
while holding a READ or WRITE lock on the uobject.
This value cannot be NULL and has no race.
- Hold the ucontext_lock and check for ufile->ucontext !NULL
This also re-implements ib_uverbs_get_ucontext() in a way that is safe
against concurrent ib_uverbs_get_context() and disassociation.
As a side effect, every access to ucontext in the commands is via
ib_uverbs_get_context() with an error check, or via the uobject, so there
is no longer any need for the core code to check ucontext on every command
call. These checks are also removed.

Introduce flow steering matcher object and its create and destroy methods.
This matcher object holds some mlx5 specific driver properties that
matches the underlay device specification when an mlx5 flow steering group
is created.
It will be used in downstream patches to be part of mlx5 specific create
flow method.
