IB driver maintains different registration and load function calls
for uplink and VF vports. This is not necessary as they only differ
with each other on their profiles.
This patch doesn't change any functionality.

The PD allocations in IB/core allows us to simplify drivers and their
error flows in their .alloc_pd() paths. The changes in .alloc_pd() go hand
in had with relevant update in .dealloc_pd().
We will use this opportunity and convert .dealloc_pd() to don't fail, as
it was suggested a long time ago, failures are not happening as we have
never seen a WARN_ON print.

When a given netdev of the GID entry is macvlan netdevice, and if the
lower netdevice is vlan device, GID entry for macvlan based IP address
needs to inherit the vlan of the lower netdevice.
Therefore, attempt to find out if the lower device exist and if so, if
it is vlan device and setup the vlan tag correctly.

All callers to ib_alloc_device() provide a larger size than struct
ib_device and rely on the fact that struct ib_device is embedded in their
driver specific structure as the first member.
Provide a safer variant of ib_alloc_device() that checks and enforces this
approach to make sure the drivers are using it right.

Two flow specifications can set the ip protocol field in
the flow table entry:
1) IB_FLOW_SPEC_TCP/UDP/GRE - set the ip protocol accordingly.
2) IB_FLOW_SPEC_IPV4/6 - has ip_protocol field for users
who want to receive specific L4 packets.
We need to avoid overriding of the ip_protocol with zeros,
in case that the user first put the L4 specification and
only then the L3.

When in switchdev mode and the add function is called by the core
level driver, make sure we only register the callbacks, but don't
create the mlx5 IB device or initialize anything. With this change
all the IB devices in switchdev mode are created only once the load
callback is invoked by the e-switch core sub-module. This follows
the design paradigm under which the all the Eth representors must
be loaded before any of IB reprs is loaded.

Danit Goldberg says:
Packet based credit mode
Packet based credit mode is an alternative end-to-end credit mode for QPs
set during their creation. Credits are transported from the responder to
the requester to optimize the use of its receive resources. In
packet-based credit mode, credits are issued on a per packet basis.
The advantage of this feature comes while sending large RDMA messages
through switches that are short in memory.
The first commit exposes QP creation flag and the HCA capability. The
second commit adds support for a new DV QP creation flag. The last commit
report packet based credit mode capability via the MLX5DV device
capabilities.

For vport repesentors, don't register any notifier, same as before, they

For slave port (mlx5_ib_multiport_info) register a different notifier
callback mlx5_ib_event_slave_port, which knows that the event is coming
for mlx5_ib_multiport_info and prepares the event job accordingly.
Before this on the event handler work we had to ask mlx5_core if this is
a slave port mlx5_core_is_mp_slave(work->dev), now it is not needed

The 'tree' data structure is very hard to build at compile time, and this
makes it very limited. The new radix tree based compiler can handle a more
complex input language that does not require the compiler to perfectly
group everything into a neat tree structure.
Instead use a simple list to describe to input, where the list elements
can be of various different 'opcodes' instructing the radix compiler what
to do. Start out with opcodes chaining to other definition lists and
chaining to the existing 'tree' definition.
Replace the very top level of the 'object tree' with this list type and
get rid of struct uverbs_object_tree_def and DECLARE_UVERBS_OBJECT_TREE.

If the firmware reports a connection width that is not 1x, 4x, 8x or 12x
it causes the driver to fail during initialization.
To prevent this failure every time a new width is introduced to the RDMA
stack, we will set a default 4x width for these widths which ar unknown to
the driver.
This is needed to allow to run old kernels with new firmware.

Devices that does not use managed affinity can not export a vector
affinity as the consumer relies on having a static mapping it can map to
upper layer affinity (e.g. sw queues). If the driver allows the user to
set the device irq affinity, then the affinitization of a long term
existing entites is not relevant.
For example, nvme-rdma controllers queue-irq affinitization is determined
at init time so if the irq affinity changes over time, we are no longer
aligned.

"This has been a smaller cycle with many of the commits being smallish
code fixes and improvements across the drivers.
- Driver updates for bnxt_re, cxgb4, hfi1, hns, mlx5, nes, qedr, and
rxe
- Memory window support in hns
- mlx5 user API 'flow mutate/steering' allows accessing the full
packet mangling and matching machinery from user space
- Support inter-working with verbs API calls in the 'devx' mlx5 user
API, and provide options to use devx with less privilege
- Modernize the use of syfs and the device interface to use attribute
groups and cdev properly for uverbs, and clean up some of the core
code's device list management
- More progress on net namespaces for RDMA devices
- Consolidate driver BAR mmapping support into core code helpers and
rework how RDMA holds poitners to mm_struct for get_user_pages
cases
- First pass to use 'dev_name' instead of ib_device->name
- Device renaming for RDMA devices"

If no-append flag is set, we will add a new FTE, instead of appending
the actions of the inserted rule when the same match already exists.
While here, move the has_flow_tag boolean indicator to be a flag too.
This patch doesn't change any functionality.
