Previously, deleting a flow steering entry only got the index.
Since the FPGA implementation of FTE's deletion might need to dig
inside the FTE itself, we would like to get the FTE's context.
Changing the interface to pass the FTE context.

The shim layer allows each namespace to define possibly different
functionality for add/delete/update commands. The shim layer
introduced here, will be used to support flow steering with the FPGA.

Previous support allowed connecting only a single QPN to the FT.
Now using a linked list multiple QPNs can be attached to the same FT.
Supporting attaching multiple underlay QPs is required for PKEY
support in which child and parent share the same FT.
The actual attaching/detaching FW commands will be called inside the
function symmetrically.
This change requires a change in IPoIB open and close functions, the
attaching/detaching to/from the FT is done each time we open/close.

Read new NIC capability field which represnts 16 MSBs of the max flow
counters number supported (max_flow_counter_31_16).
Backward compatibility with older firmware is preserved, the modified
driver reads max_flow_counter_31_16 as 0 from the older firmware and
uses up to 64K counters.
Changed flow counter id from 16 bits to 32 bits. Backward compatibility
with older firmware is preserved as we kept the 16 LSBs of the counter
id in place and added 16 MSBs from reserved field.
Changed the background bulk reading of flow counters to work in chunks
of at most 32K counters, to make sure we don't attempt to allocate very
large buffers.

Root flow table is dynamically changed by the underlying flow steering
layer, and IPoIB/ULPs have no idea what will be the root flow table in
the future, hence we need a dynamic infrastructure to move Underlay QPs
with the root flow table.

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
functionality.

The alloc and dealloc encap commands will be used in the mlx5e driver,
as such, declare them in a common header file.
Also, rename the functions: mlx5_cmd_{de}alloc_encap is replaced with
mlx5_encap_{de}alloc.

Add interfaces to allow the creation and destruction of a
LAG demux flow table.
It is a special flow table used during LAG for redirecting
non user-mode packets from PF0 to PF1 root ft, if a packet was
received on phys port two.

This commit utilize the ability of ConnectX-4 to bulk read flow counters.
Few bulk counter queries could be done instead of issuing thousands of
firmware commands per second to get statistics of all flows set to HW,
such as those programmed when we offload tc filters.
Counters are stored sorted by hardware id, and queried in blocks (id +
number of counters).
Due to hardware requirement, start of block and number of counters in a
block must be four aligned.

When adding a flow steering rule with a counter, need to supply a
destination of type MLX5_FLOW_DESTINATION_TYPE_COUNTER, with a pointer
to a struct mlx5_fc.
Also, MLX5_FLOW_CONTEXT_ACTION_COUNT bit should be set in the action.

Update the relevant flow steering device structs and commands to
support vport.
Update the flow steering core API to receive vport number.
Add ingress and egress ACL flow table name spaces.
Add ACL flow table support:
* ACL (Access Control List) flow table is a table that contains
only allow/drop steering rules.
* We have two types of ACL flow tables - ingress and egress.
* ACLs handle traffic sent from/to E-Switch FDB table, Ingress refers to
traffic sent from Vport to E-Switch and Egress refers to traffic sent
from E-Switch to vport.
* Ingress ACL flow table allow/drop rules is checked against traffic
sent from VF.
* Egress ACL flow table allow/drop rules is checked against traffic sent
to VF.

Flow tables from different priorities should be chained together.
When a packet arrives we search for a match in the
by-pass flow tables (first we search for a match in priority 0
and if we don't find a match we move to the next priority).
If we can't find a match in any of the bypass flow-tables, we continue
searching in the flow-tables of the next priority, which are the
kernel's flow tables.
Setting the miss flow table in a new flow table to be the next one in
the list is performed via create flow table API. If we want to change an
existing flow table, for example in order to point from an
existing flow table to the new next-in-list flow table, we use the
modify flow table API.

Introduce the modify flow table command. This command is used when
we want to change the next flow table of an existing flow table.
The next flow table is defined as the table we search (in order
to find a match), if we couldn't find a match in any of the flow table
entries in the current flow table.

The root Flow Table for each Flow Table Type is defined,
by default, as the Flow Table with level 0.
In order not to use an empty flow tables and introduce new hops,
but still preserve space for flow-tables that have a priority
greater(lower number) than the current flow table, we introduce this
new set root flow table command.
This command tells the HW to start matching packets from the
assigned root flow table.
This command is used when we create new flow table with level lower than the
current lowest flow table or it is the first flow table.
