86f5d0f3d4 net/mlx5: Introduce egress acl forward-to-vport capability
Add HCA_CAP.egress_acl_forward_to_vport field to check whether HW
supports e-switch vport's egress acl to forward packets to other
e-switch vport or not.

By default E-Switch egress ACL forwards eswitch vports egress packets
to their corresponding NIC/VF vports.

With this cap enabled, the driver is allowed to alter this behavior
and forward packets to arbitrary NIC/VF vports with the following
limitations:

   a. Multiple processing paths are supported if all of the following
      conditions are met:
      - HCA_CAP.egress_acl_forward_to_vport is set ==1.
      - A destination of type Flow Table only appears once, as the
        last destination in the list.
      - Vport destination is supported if
        HCA_CAP.egress_acl_forward_to_vport==1. Vport must not be
        the Uplink.
   b. Flow_tag not supported.
   c. This table is only applicable after an FDB table is created.
   d. Push VLAN action is not supported.
   e. Pop VLAN action cannot be added concurrently to this table and
      FDB table.

This feature will be used during port failover in bonding scenario
where two VFs representors are bonded to handle failover egress traffic
(VM's ingress/receive traffic).

1326034b3c net/mlx5: Expose raw packet pacing APIs
Expose raw packet pacing APIs to be used by DEVX based applications.
The existing code was refactored to have a single flow with the new raw
APIs.

The new raw APIs considered the input of 'pp_rate_limit_context', uid,
'dedicated', upon looking for an existing entry.

This raw mode enables future device specification data in the raw
context without changing the existing logic and code.

The ability to ask for a dedicated entry gives control for application
to allocate entries according to its needs.

A dedicated entry may not be used by some other process and it also
enables the process spreading its resources to some different entries
for use different hardware resources as part of enforcing the rate.

The counter per entry was changed to be u64 to prevent any option to
overflow.

Pull rdma updates from Jason Gunthorpe:
 "A very quiet cycle with few notable changes. Mostly the usual list of
  one or two patches to drivers changing something that isn't quite rc
  worthy. The subsystem seems to be seeing a larger number of rework and

  prepping their drivers for new silicon.

db849faa9b net/mlx5e: Rx, Fix checksum calculation for new hardware
CQE checksum full mode in new HW, provides a full checksum of rx frame.
Covering bytes starting from eth protocol up to last byte in the received
frame (frame_size - ETH_HLEN), as expected by the stack.

Fixing up skb->csum by the driver is not required in such case. This fix
is to avoid wrong checksum calculation in drivers which already support
the new hardware with the new checksum mode.

1dd7382b1b net/mlx5: Introduce VHCA tunnel device capability
When using the device emulation feature (introduced in Bluefield-1 SOC),
a privileged function (the device emulation manager) will be able to
create a channel to execute commands on behalf of the emulated function.

This channel will be a general object of type VHCA_TUNNEL that will have
a unique ID for each emulated function. This ID will be passed in each
cmd that will be issued by the emulation SW in a well known offset in
the command header.

This channel is needed since the emulated function doesn't have a normal
command interface to the HCA HW, but some basic configuration for that
function is needed (e.g. initialize and enable the HCA). For that matter,
a specific command-set was defined and only those commands will be issued
by the HCA.

5ccf2770e8 net/mlx5: Don't handle VF func change if host PF is disabled
When ECPF eswitch manager is at offloads mode, it monitors functions
changed event from host PF side and acts according to the number of
VFs enabled/disabled.

As ECPF and host PF work in two independent hosts, it's possible that
host PF OS reboots but ECPF system is still kept on and continues
monitoring events from host PF. When kernel from host PF side is
booting, PCI iov driver does sriov_init and compute_max_vf_buses by
iterating over all valid num of VFs. This triggers FLR and generates
functions changed events, even though host PF HCA is not enabled at
this time. However, ECPF is not aware of this information, and still
handles these events as usual. ECPF system will see massive number of
reps are created, but destroyed immediately once creation finished.

To eliminate this noise, a bit is added to host parameter context to
indicate host PF is disabled. ECPF will not handle the VF changed
event if this bit is set.

a82e0b5bda net/mlx5: Added MCQI and MCQS registers' description to ifc
Given a fw component index, the MCQI register allows us to query
this component's information (e.g. its version and capabilities).

Given a fw component index, the MCQS register allows us to query the
status of a fw component, including its type and state
(e.g. PRESET/IN_USE).
It can be used to find the index of a component of a specific type, by
sequentially increasing the component index, and querying each time the
type of the returned component.
If max component index is reached, 'last_index_flag' is set by the HCA.

These registers' description was added to query the running and pending
fw version of the HCA.
