Flow steering specifications structures were implemented as in an
extensible way that allows one to add new filters and new fields
to existing filters.
These specifications have never been extended, therefore the
kernel flow specifications size and the user flow specifications size
were must to be equal.
In downstream patch, the IPv4 flow specifications type is extended to
support TOS and TTL fields.
To support an extension we change the flow specifications size
condition test to be as following:
* If the user flow specifications is bigger than the kernel
specifications, we verify that all the bits which not in the kernel
specifications are zeros and the flow is added only with the kernel
specifications fields.
* Otherwise, we add flow rule only with the user specifications fields.
User space filters must be aligned with 32bits.

Counters weren't updated due to raw packet QPs' traffic since the
counter-id was not associated with the QP. Added support for
associating the q-counter-id with the raw packet QP. The attachment
is done only when changing RQ raw packet QP state from RST to INIT
in modify-RQ command. FW support is required for the above, without
this support raw packet QP counters will not count.

Expose RSS related capabilities on both IB and vendor channels.
In addition to the IB capabilities the driver reports some extra
capabilities on its vendor channel:
- Bit mask of the supported types of hash functions.
- Bit mask of the supported RX fields that can participate
in the RX hashing.
Those capabilities are applicable only when the link layer
is Ethernet.

We now only use it from ib_alloc_pd to create a local DMA lkey if the
device doesn't provide one, or a global rkey if the ULP requests it.
This patch removes ib_get_dma_mr and open codes the functionality in
ib_alloc_pd so that we can simplify the code and prevent abuse of the
functionality. As a side effect we can also simplify things by removing
the valid access bit check, and the PD refcounting.
In the future I hope to also remove the per-PD global MR entirely by
shifting this work into the HW drivers, as one step towards avoiding
the struct ib_mr overload for various different use cases.

Instead of exposing ib_get_dma_mr to ULPs and letting them use it more or
less unchecked, this moves the capability of creating a global rkey into
the RDMA core, where it can be easily audited. It also prints a warning
everytime this feature is used as well.

This has two reasons: a) to clearly mark that drivers don't have any
business using it, and b) because we're going to use it for the
(dangerous) global rkey soon, so that drivers don't create on themselves.

This patch is meant to add support of ACPI to the Hisilicon RoCE
driver.
Changes done are primarily meant to detect the type and then either
use DT specific or ACPI spcific functions. Where ever possible,
this patch tries to make use of Unified Device Property Interface
APIs to support both DT and ACPI through single interface.
This patch depends upon HNS ethernet driver to Reset RoCE. This
function within HNS ethernet driver has also been enhanced to
support ACPI and is part of other accompanying patch with this
patch-set.
NOTE: The changes in this patch are done over below branch,

In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network
Subsystem and is dependent upon DSAF module. Therefore, certain
functions like RESET are exposed through the common registers of
HNS DSAF module which are memory-mapped by the HNS driver and
currently can only be accessed through DT/syscon interface.
This patch adds the support of ACPI to the existing RoCE reset
function in the HNS driver(please refer NOTE 2). Hisilicon RoCE
driver (please refer NOTE 1) shall call this reset function during
probe time to reset the RoCE Engine.
The HNS Reset function indirectly ends up in calling the _DSM()
function part of the DSDT ACPI Table. Actual reset functionality
for ACPI is implemented within the ACPI DSDT Table which also has
been enhanced to support this change.
Support of ACPI in the HNS RoCE driver shall be pushed through a
different accompanying below patch:
"IB/hns: Add support of ACPI to the Hisilicon RoCE Driver"
NOTE 1: HNS RoCE driver has already been accepted by its maintainer
Doug Ledford<dledford@redhat.com>. Please refer below link:

NOTE 2: RoCE reset function patch has been accepted and now is
part of the net-next:
