Add a vf parameter to mlx5_core_query_vport_counter so we can call it to
query counters of virtual functions. Also update current users of the
API.
PFs may call mlx5_core_query_vport_counter with other_vport set to
indicate that they are querying a virtual function. The virtual
function to be queried is given by the vf parameter. Virtual function
numbering is zero based so the first VF is 0 and so on. When a PF
queries its own function, the other_vport parameter is cleared.

Pull rdma updates from Doug Ledford:
"Initial roundup of 4.5 merge window patches
- Remove usage of ib_query_device and instead store attributes in
ib_device struct
- Move iopoll out of block and into lib, rename to irqpoll, and use
in several places in the rdma stack as our new completion queue
polling library mechanism. Update the other block drivers that
already used iopoll to use the new mechanism too.
- Replace the per-entry GID table locks with a single GID table lock
- IPoIB multicast cleanup
- Cleanups to the IB MR facility
- Add support for 64bit extended IB counters
- Fix for netlink oops while parsing RDMA nl messages
- RoCEv2 support for the core IB code
- mlx4 RoCEv2 support
- mlx5 RoCEv2 support
- Cross Channel support for mlx5
- Timestamp support for mlx5
- Atomic support for mlx5
- Raw QP support for mlx5
- MAINTAINERS update for mlx4/mlx5
- Misc ocrdma, qib, nes, usNIC, cxgb3, cxgb4, mlx4, mlx5 updates
- Add support for remote invalidate to the iSER driver (pushed
through the RDMA tree due to dependencies, acknowledged by nab)
- Update to NFSoRDMA (pushed through the RDMA tree due to
dependencies, acknowledged by Bruce)"

A mlx5 Ethernet port must be explicitly enabled for RoCE.
When RoCE is not enabled on the port, the NIC will refuse to create
QPs attached to it and incoming RoCE packets will be considered by the
NIC as plain Ethernet packets.

Introduce a new function called mlx5_query_nic_vport_context().
This function gets all the NIC vport attributes from the device.
The MAC address is just one of the NIC vport attributes, so
mlx5_query_nic_vport_mac_address() is now just a wrapper function
above mlx5_query_nic_vport_context().
More NIC vport attributes will be used in following commits.

In preparation for SR-IOV we add here an API to enable each e-switch
client (PF/VF) to configure its L2 MAC addresses and for the e-switch
manager (usually the PF) to access them in order to be able to
configure them into the e-switch.
Therefore we now pass vport num parameter to
mlx5_query_nic_vport_context, so PF can access other vports contexts.

Added the implementation for the following commands:
1. QUERY_HCA_VPORT_GID
2. QUERY_HCA_VPORT_PKEY
3. QUERY_HCA_VPORT_CONTEXT
They will be needed when we move to work with ISSI > 0 in the IB driver too.

Move the vport header file to be under include/linux/mlx5, such that
the mlx5 IB can use it as well.
Also add nic_ prefix to the vport NIC commands to differeniate between
HCA vport commands and NIC vport commands.

This patch contains the resource handling files:
- flow_table.c: This file contains the code to handle the low level API
to configure hardware flow table. It is separated from
the flow_table_en.c, because it will be used in the
future by Raw Ethernet QP in mlx5_ib too.
- en_flow_table.[ch]: Ethernet flow steering handling. The flow table
object contain a mapping between flow specs and TIRs.
This mechanism will be used also to configure e-switch
in the future, when SR-IOV support will be added.
- transobj.[ch] - Low level functions to create/modify/destroy the
transport objects: RQ/SQ/TIR/TIS
- vport.[ch] - Handle attributes of a virtual port (vPort) in the
embedded switch. Currently this switch is a passthrough, until SR-IOV
support will be added.
