This commit adds counters support when creating flows via direct
verbs. The implementation uses devx interface in order to create
query and delete the counters.
This support requires MLNX_OFED_LINUX-4.5-0.1.0.1 installation.

This patch implements the set of actions to support offload
of packet header modifications to MLX5 NIC.
Implementation is based on RFC [1].

As described in series starting at [1], it adds option to set
metadata value as match pattern when creating a new flow rule.
This patch adds metadata support in mlx5 driver, in two parts:
- Add the validation and setting of metadata value in matcher,
when creating a new flow rule.
- Add the passing of metadata value from mbuf to wqe when
indicated by ol_flag, in different burst functions.

This commit handles the translation of the requested flow into Direct
Verbs API.
The Direct Verbs introduce the matcher object which acts as shared mask
for all flows that are using the same mask. So in this commit we
translate the item and get in return a matcher and the value that should
be matched.

This function allocates the Direct Verbs device flow, and
introduce the relevant PRM structures.
This commit also adds the matcher object. The matcher object acts as a
mask and should be shared between flows. For example all rules that
should match source IP with full mask should use the same matcher. A
flow that should match dest IP or source IP but without full mask should
have a new matcher allocated.

Multi-Packet Rx Queue (MPRQ a.k.a Striding RQ) can further save PCIe
bandwidth by posting a single large buffer for multiple packets. Instead of
posting a buffer per a packet, one large buffer is posted in order to
receive multiple packets on the buffer. A MPRQ buffer consists of multiple
fixed-size strides and each stride receives one packet.
Rx packet is mem-copied to a user-provided mbuf if the size of Rx packet is
comparatively small, or PMD attaches the Rx packet to the mbuf by external
buffer attachment - rte_pktmbuf_attach_extbuf(). A mempool for external
buffers will be allocated and managed by PMD.

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:

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)

ConnectX-5 supports enhanced version of multi-packet send (MPS). An MPS Tx
descriptor can carry multiple packets either by including pointers of
packets or by inlining packets. Inlining packet data can be helpful to
better utilize PCIe bandwidth. In addition, Enhanced MPS supports hybrid
mode - mixing inlined packets and pointers in a descriptor. This feature is
enabled by default if supported by HW.

Rework Work Queue Element (aka WQE) structures to fit PMD needs.
A WQE is an aggregation of 16 bytes elements known as "data segments"
(aka dseg).
The only common part is the first two elements i.e. the control one to
define the job type, and the Ethernet segment which embed offload requests
with other information, after that, it can have:
- a raw data packet,
- a data pointer to the packet itself,
- both.

These errors can be removed by changing the "-pedantic" to "-Wpedantic".
