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.

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.

Prior to this patch we assumed that modify QP commands have the
same layout.
In ConnectX-4 for each QP transition there is a specific command
and their layout can vary.
e.g: 2err/2rst commands don't have QP context in their layout and before
this patch we posted the QP context in those commands.
Fortunately the FW only checks the suffix of the commands and executes
them, while ignoring all invalid data sent after the valid command
layout.
This patch removes mlx5_modify_qp_mbox_in and changes
mlx5_core_qp_modify to receive the required transition and QP context
with opt_param_mask if needed. This way the caller is not required to
provide the command inbox layout and it will be generated automatically.
mlx5_core_qp_modify will generate the command inbox/outbox layouts
according to the requested transition and will fill the requested
parameters.

Number of outstanding_pi may overflow and as a result may indicate that
there are no elements in the queue. The effect of doing this is that the
MAD layer will get stuck waiting for completions. The MAD layer will
think that the QP is full - because it didn't receive these completions.
This fix changes it so the outstanding_pi number is increased
with 32-bit wraparound and is not limited to max_send_wr so
that the difference between outstanding_pi and outstanding_ci will
really indicate the number of outstanding completions.

Enable mlx5 based hardware to report TCP segmentation offload (TSO)
capabilities from kernel to user space. A TSO enabled NIC will accept
big chunks of data with sizes greater than MTU for TCP traffic. The TSO
engine will break the data into separate packets and will insert headers
automatically.
The capabilities are exposed to user space through query_device by uhw
directly. The following capabilities are reported:
1. The maximum payload size in bytes supported for segmentation by TSO
engine.
2. Bitmap showing which QP types are supported by TSO operation. The bitmap
is built by members from 'enmu ib_qp_type'. For example, similar code
should be performed if UD QP is supported:
supported_qpts |= 1 << IB_QPT_UD;
To make user-space library aware of whether kernel supports uhw or not, a
new flag: cmds_supp_uhw will be returned back to user-space through
alloc_ucontext.

The driver exposes interfaces that directly relate to HW state.
Upon fatal error, consumers of these interfaces (ULPs) that rely
on completion of all their posted work-request could hang, thereby
introducing dependencies in shutdown order. To prevent this from
happening, we manage the relevant resources (CQs, QPs) that are used
by the device. Upon a fatal error, we now generate simulated
completions for outstanding WQEs that were not completed at the
time the HW was reset.
It includes invoking the completion event handler for all involved
CQs so that the ULPs will poll those CQs. When polled we return
simulated CQEs with IB_WC_WR_FLUSH_ERR return code enabling ULPs
to clean up their resources and not wait forever for completions
upon receiving remove_one.
The above change requires an extra check in the data path to make
sure that when device is in error state, the simulated CQEs will
be returned and no further WQEs will be posted.

Implements the IB core disassociate_ucontext API.
The driver detaches the HW resources for a given user context to
prevent a dependency between application termination and device
disconnect. This is done by managing the VMAs that were mapped
to the HW bars such as doorbell and blueflame. When need to detach,
remap them to an arbitrary kernel page returned by the zap API.

A QP can be created without internal WQs "packaged" inside it,
this QP can be configured to use "external" WQ object as its
receive/send queue.
WQ is a necessary component for RSS technology since RSS mechanism
is supposed to distribute the traffic between multiple
Receive Work Queues
Receive WQs are implemented by RQs.
Implement the WQ creation, modification and destruction verbs.

If the caller specified IB_SEND_FENCE in the send flags of the work
request and no previous work request stated that the successive one
should be fenced, the work request would be executed without a fence.
This could result in RDMA read or atomic operations failure due to a MR
being invalidated. Fix this by adding the mlx5 enumeration for fencing
RDMA/atomic operations and fix the logic to apply this.

Userspace flag IBV_QP_ALT_PATH is supposed to set the alternate path
including fields alt_pkey_index and alt_timeout.
Added IB_QP_PKEY_INDEX and IB_QP_TIMEOUT to the attribute mask when
calling mlx5_set_path for the alternate path to force setting the
alt_pkey_index and alt_timeout values.

Pkey index fields in the QP context path record are extended to 16
bits, as required by IB spec (version 1.3).
This change affects all QP commands which include path records.
To enable this change, moved the free adaptive routing flag bit
(free_ar) to the most significant byte of the QP path record.
