Instead MLX5_TOTAL_VPORTS, use mlx5_eswitch_get_total_vports().
mlx5_eswitch_get_total_vports() in subsequent patch accounts for SF
vports as well.
Expanding MLX5_TOTAL_VPORTS macro would require exposing SF internals to
more generic vport.h header file. Such exposure is not desired.
Hence a mlx5_eswitch_get_total_vports() is introduced.

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.

In vport metadata matching, source port number is replaced by metadata.
While FW has no idea about what it is in the metadata, a syndrome will
happen. Specify a known origin to avoid the syndrome.
However, there is no functional change because ANY_VPORT (0) is filled
in flow_source, the same default value as before, as a pre-step towards
metadata matching for fast path.
There are two other values can be filled in flow_source. When setting
0x1, packet matching this rule is from uplink, while 0x2 is for packet
from other local vports.

When a dual-port VHCA sends a RoCE packet on its non-native port, and the
packet arrives to its affiliated vport FDB, a mismatch might occur on the
rules that match the packet source vport as it is not represented by single
VHCA only in this case. So we change to match on metadata instead of source
vport.
To do that, a rule is created in all vports and uplink ingress ACLs, to
save the source vport number and vhca id in the packet's metadata in order
to match on it later.
The metadata register used is the first of the 32-bit type C registers. It
can be used for matching and header modify operations. The higher 16 bits
of this register are for vhca id, and the lower 16 ones is for vport
number.
This change is not for dual-port RoCE only. If HW and FW allow, the vport
metadata matching is enabled by default.

This new WR will be used to perform PI (protection information) handover
using the new API. Using the new API, the user will post a single WR that
will internally perform all the needed actions to complete PI operation.
This new WR will use a memory region that was allocated as
IB_MR_TYPE_INTEGRITY and was mapped using ib_map_mr_sg_pi to perform the
registration. In the old API, in order to perform a signature handover
operation, each ULP should perform the following:
1. Map and register the data buffers.
2. Map and register the protection buffers.
3. Post a special reg WR to configure the signature handover operation
layout.
4. Invalidate the signature memory key.
5. Invalidate protection buffers memory key.
6. Invalidate data buffers memory key.
In the new API, the mapping of both data and protection buffers is
performed using a single call to ib_map_mr_sg_pi function. Also the
registration of the buffers and the configuration of the signature
operation layout is done by a single new work request called
IB_WR_REG_MR_INTEGRITY.
This patch implements this operation for mlx5 devices that are capable to
offload data integrity generation/validation while performing the actual
buffer transfer.
This patch will not remove the old signature API that is used by the iSER
initiator and target drivers. This will be done in the future.
In the internal implementation, for each IB_WR_REG_MR_INTEGRITY work
request, we are using a single UMR operation to register both data and
protection buffers using KLM's.
Afterwards, another UMR operation will describe the strided block format.
These will be followed by 2 SET_PSV operations to set the memory/wire
domains initial signature parameters passed by the user.
In the end of the whole transaction, only the signature memory key
(the one that exposed for the RDMA operation) will be invalidated.

To avoid any ambiguity between vport index and vport number,
rename functions that had vport, to vport_num or vport_index appropriately.
vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return
type to u16.
vport_index is an int in vport array. Hence change input type of vport
index in mlx5_eswitch_index_to_vport_num() to int.
Correct multiple eswitch representor interfaces use type u16 of
rep->vport as type int vport_index.
Send vport FW commands with correct eswitch u16 vport_num instead
host int vport_index.
