When LAG is active, port up/down events should be triggered
by tracking the LAG master, and not one of the two slave
netdevs.
In the same manner, ib_query_port() should return the details
of the LAG master.

This is done in two steps:
1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from
both ports arriving on PF0 root flowtable, so we will be able to catch
all raw-eth traffic on PF0.
2) Creation of LAG demux flowtable in order to direct all non-raw-eth
traffic back to its source port, assuring that normal Ethernet
traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port
state, it makes sense to propagate the port up/down events to ib_core
when the netdev port state changes, instead of relying on traditional
core events.
This also keeps both the event and ib_query_port() synchronized.

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.

- Bit mask of the supported RX fields that can participate

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

This has two reasons: a) to clearly mark that drivers don't have any

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:
https://www.spinics.net/lists/linux-rdma/msg38850.html
NOTE 2: RoCE reset function patch has been accepted and now is

Available on dual port cards only, this feature keeps
track, using netdev LAG events, of the bonding
and link status of each port's PF netdev.
When both of the card's PF netdevs are enslaved to the
same bond/team master, and only them, LAG state
is active.
During LAG, only one IB device is present for both ports.
In addition to the above, this commit includes FW commands
used for managing the LAG, new facilities for adding and removing
a single device by interface, and port remap functionality according to
bond events.
Please note that this feature is currently used only for mimicking
Ethernet bonding for RoCE - netdevs functionality is not altered,
and their bonding continues to be managed solely by bond/team driver.

Allows to port remap QPs and TISes, overriding their
tx_affinity behavior.
- MODIFY_LAG
Remap QPs and TISes to another port.
- QUERY_LAG
Query whether LAG mode is active.
- DESTROY_LAG
HW exits LAG mode, returning to non-LAG behavior.
- CREATE_VPORT_LAG
Merge Ethernet flow steering, such that traffic received on port
two jumps to PF0 root flow table.
Available only in LAG mode.
- DESTROY_VPORT_LAG
Ethernet flow steering returns to non-LAG behavior.
Caps added:
- lag_master
Driver is in charge of managing the LAG.
This is currently the only option.
- num_lag_ports
LAG is supported only if this field's value is 2.
Other fields:
- QP/TIS tx port affinity
During LAG, this field controls on which port a QP or TIS resides.
- TIS strict tx affinity
When this field is set, the TIS will not be subject to port remap by
CREATE_LAG/MODIFY_LAG.
- LAG demux flow table
Flow table used for redirecting non user-space traffic back to
PF1 root flow table, if the packet was received on port two.

Replaced mlx5_query_port_proto_oper with separate functions per link
type. The functions should take different arguments so no point in
trying to unite them.

The mlx5e_link_mode enumeration will also be used in mlx5_ib for RoCE.
This patch moves the enumeration to the mlx5 driver port header file.
