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).

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.

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.
