When the "ib_virt" cap is set, configuration of port capabilities need
to be done through mlx5_core_modify_hca_vport_context.
Since modify_hca_vport_context accepts mask and value, there is no need
to read the port capabilities and calculate the new cap values so we
avoid the mutex when ib_virt is set.

Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.
Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.
Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.
This patch doesn't add any new functionality.

For some mlx5 HW models (CX4, CX4Lx), the VF driver needs to put part
of the packet headers on the TX descriptor so the e-switch can do proper
matching and steering. This is called "min-inline", it's advertized to
the VF by the FW and also enforced on them by the HW, such that if they
don't obey, their packets are dropped.
SRIOV VF libmlx5 instances should take into account the min-inline
value of their vports. For that end, we provide this value through
the vendor response part of init_ucontext command.
The min inline value is reported in a way which will let newer libmlx5
instances realize that they are running over an older kernel and act
accordingly (e.g apply some educated guess).

Current check requests that new fields in struct
mlx5_ib_alloc_ucontext_req_v2 that are not known to the driver be zero.
This was introduced so new libraries passing additional information to
the kernel through struct mlx5_ib_alloc_ucontext_req_v2 will be notified
by old kernels that do not support their request by failing the
operation. This schecme is problematic since it requires libmlx5 to issue
the requests with descending input size for struct
mlx5_ib_alloc_ucontext_req_v2.
To avoid this, we require that new features that will obey the following
rules:
If the feature requires one or more fields in the response and the at
least one of the fields can be encoded such that a zero value means the
kernel ignored the request then this field will provide the indication
to the library. If no response is required or if zero is a valid
response, a new field should be added that indicates to the library
whether its request was processed.

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Due to various issues, I've been away and couldn't send a pull request

Most of the code has had plenty of soak time at the various vendor's
testing setups, so I doubt there will be another -rc pull request this

In order to support steering rules which add encapsulation headers,
encap_id parameter is needed.
Add new mlx5_flow_act struct which holds action related parameter:
action, flow_tag and encap_id. Use mlx5_flow_act struct when adding a new
steering rule.
This patch doesn't change any functionality.

When creating flow tables, allow the caller to specify creation flags.
Currently no flags are used and as such this patch doesn't add any new

Mellanox mlx5 core driver updates 2016-10-25
This series contains some updates and fixes of mlx5 core and
IB drivers with the addition of two features that demand
new low level commands and infrastructure updates.
- SRIOV VF max rate limit support
- mlx5e tc support for FWD rules with counter.
Needed for both net and rdma subsystems.
Updates and Fixes:
From Saeed Mahameed (2):
- mlx5 IB: Skip handling unknown mlx5 events
- Add ConnectX-5 PCIe 4.0 VF device ID
From Artemy Kovalyov (2):
- Update struct mlx5_ifc_xrqc_bits
- Ensure SRQ physical address structure endianness
From Eugenia Emantayev (1):
- Fix length of async_event_mask
New Features:
From Mohamad Haj Yahia (3): mlx5 SRIOV VF max rate limit support
- Introduce TSAR manipulation firmware commands
- Introduce E-switch QoS management
- Add SRIOV VF max rate configuration support
From Mark Bloch (7): mlx5e Tc support for FWD rule with counter
- Don't unlock fte while still using it
- Use fte status to decide on firmware command
- Refactor find_flow_rule
- Group similar rules under the same fte
- Add multi dest support
- Add option to add fwd rule with counter
- mlx5e tc support for FWD rule with counter
Mark here fixed two trivial issues with the flow steering core, and did
some refactoring in the flow steering API to support adding mulit destination
rules to the same hardware flow table entry at once. In the last two patches
added the ability to populate a flow rule with a flow counter to the same flow entry.
V2: Dropped some patches that added new structures without adding any usage of them.
Added SRIOV VF max rate configuration support patch that introduces
the usage of the TSAR infrastructure.
Added flow steering fixes and refactoring in addition to mlx5 tc
support for forward rule with counter.

Currently when calling mlx5_add_flow_rule we accept
only one flow destination, this commit allows to pass
multiple destinations.
This change forces us to change the return structure to a more
flexible one. We introduce a flow handle (struct mlx5_flow_handle),
it holds internally the number for rules created and holds an array
where each cell points the to a flow rule.
From the consumers (of mlx5_add_flow_rule) point of view this
change is only cosmetic and requires only to change the type
of the returned value they store.
From the core point of view, we now need to use a loop when
allocating and deleting rules (e.g given to us a flow handler).

- Updates to mlx5
- Updates to mlx4 (two conflicts, both minor and easily resolved)
- Updates to iw_cxgb4 (one conflict, not so obvious to resolve, proper
resolution is to keep the code in cxgb4_main.c as it is in Linus'
tree as attach_uld was refactored and moved into cxgb4_uld.c)
- Improvements to uAPI (moved vendor specific API elements to uAPI area)
- Add hns-roce driver and hns and hns-roce ACPI reset support
- Conversion of all rdma code away from deprecated
create_singlethread_workqueue
- Security improvement: remove unsafe ib_get_dma_mr (breaks lustre in
staging)

This patch decouples and moves vendors specific structures to
common UAPI folder which will be visible to all consumers.
These structures are used by user-space library driver
(libmlx5) and currently manually copied to that library.
This move will allow cross-compile against these files and
simplify introduction of vendor specific data.
