This removes the dependency on specific Mellanox OFED libraries by
using the upstream rdma-core and linux upstream community code.
Both rdma-core upstream and Mellanox OFED are Linux user-space packages:
1. Rdma-core is Linux upstream user-space package.(Generic)
2. Mellanox OFED is Mellanox's Linux user-space package.(Proprietary)
The difference between the two are the APIs towards the kernel.
Support for x86-32 is removed due to issues in rdma-core library.
ICC compilation will be supported as soon as the following patch is
integrated in rdma-core:

- Use rte_malloc() instead of malloc() for the per device 'vdev' structure
so that it can be shared across processes.
- Only initialize the device if the process type is RTE_PROC_PRIMARY
- Only allow the primary process to do queue setup, start/stop, promisc
allmulticast, mac add/del, mtu.

Mellanox NICs has a limitation on the number of mbuf segments a multi
segment mbuf can have. The max number depends on the Tx offloads
requested.
The current code not enforce such limitation, which might cause
malformed work requests to be written to the device.
This commit adds verification for the number of mbuf segments posted
to the device. In case of overflow the packet will not be sent.
In addition update the nic documentation with the limitation.
Considering device limitation is 63 data segments in a work request, the
maximum number of segment in mbuf was calculated taking TSO as the worst
case:
max_nb_segs = 63 - (control_segment + ethernet segment +
TSO headers inline + inline segment +
extra inline to align to cacheline)

Extend the LSC event handling to support the device removal as well.
The mlx5 event handling has been made capable of receiving and
signaling several event types at once.
This support includes next:
1. Removal event detection according to the user configuration.
2. Calling to all registered mlx5 removal callbacks.
3. Capabilities extension to include removal interrupt handling.

NFP PMD implement now PF and VF drivers. Although the driver
functionality is the same by now, except for initialization, it
will change with future PF additions.
A new feature is required for describing the firmware upload
capability coming with the NFP PF now, so the PF file will be
updated soon in another patch.
SRIOV is not supported by the PF yet, and it is wrong to include it
as a VF driver feature, so none of the files have such a feature.

The Verbs RSS API used in this PMD is now obsolete. It is superseded by an
enhanced API with fewer constraints already used in the mlx5 PMD.
Drop RSS support in preparation for a major refactoring. The ability to
configure several Rx queues is retained, these can be targeted directly by
creating specific flow rules.
There is no need for "ignored" Rx queues anymore since their number is no
longer limited to powers of two.

The patch simplifies DPDK applications analysis for developers which use
Intel® VTune Amplifier.
The empty cycles are such iterations that yielded no RX packets. As far as
DPDK is running in poll mode, wasting cycles is equal to wasting CPU time.
Tracing such iterations can identify that device is underutilized. Tracing
empty cycles becomes even more critical if a system uses a lot of Ethernet
ports.
The patch gives possibility to analyze empty cycles without changing
application code. All needs to be done is just to reconfigure and rebuild
the DPDK itself with CONFIG_RTE_ETHDEV_PROFILE_ITT_WASTED_RX_ITERATIONS
enbled. The important thing here is that this does not affect DPDK code.
The profiling code is not being compiled if user does not specify config
flag.
The patch provides common way to inject RX queues profiling and VTune
specific implementation.

This commit fixes an issue in the service runner function,
where the atomic value was not cleared on exiting the service
function. This resulted in future attempts to run the service
to appear like the function was running, however it was in
reality deadlocked.
This commit refactors the atomic handling to be more readable,
by splitting the implementation code into a new static inline
function. The remaining flow control of atomics in the existing
function is refactored for readability.
