ethdev: add mbuf fast free Tx offload
PMDs which expose this offload cap supports optimization for fast release
of mbufs following successful Tx.
Such optimization requires that per queue, all mbufs come from the same
mempool and has refcnt = 1.

ethdev: introduce Tx queue offloads API
Introduce a new API to configure Tx offloads.
In the new API, offloads are divided into per-port and per-queue
offloads. The PMD reports capability for each of them.
Offloads are enabled using the existing DEV_TX_OFFLOAD_* flags.
To enable per-port offload, the offload should be set on both device
configuration and queue configuration. To enable per-queue offload, the
offloads can be set only on queue configuration.
In addition the Tx offloads will be disabled by default and be
enabled per application needs. This will much simplify PMD management of
the different offloads.
Applications should set the ETH_TXQ_FLAGS_IGNORE flag on txq_flags
field in order to move to the new API.
The old Tx offloads API is kept for the meanwhile, in order to enable a
smooth transition for PMDs and application to the new API.

At present, creating bonding devices using --vdev is broken for PMD like
mlx5 as it is neither UIO nor VFIO based and hence PMD driver is unknown
to find_port_id_by_pci_addr(), as below.
PMD: bond_ethdev_parse_slave_port_kvarg(150) - Invalid slave port value
(<PCI ID>) specified
EAL: Failed to parse slave ports for bonded device net_bonding0
This patch fixes parsing PCI ID from bonding device params by verifying
it in RTE PCI bus, rather than checking dev->kdrv.
This patch also adds configuration necessary for compilation of DPAA
Mempool driver into the DPAA specific config file.
CONFIG_RTE_MBUF_DEFAULT_MEMPOOL_OPS=dpaa is also configured to allow
applications to use DPAA mempool as default.
This Mempool driver works with DPAA BMan hardware block. This block
manages data buffers in memory, and provides efficient interface with
other hardware and software components for buffer requests.
This patch adds support for BMan. Compilation would be enabled in
subsequent patches.
Now that QBMAN (QMAN, BMAN) and FMAN drivers are available, this patch
integrates the DPAA Bus driver for using the drivers for scanning
devices and calling the PMD registered probe callbacks.
The Buffer Manager (BMan) is a hardware buffer pool management block that
allows software and accelerators on the datapath to acquire and release
buffers in order to build frames.
The Queue Manager (QMan) is a hardware queue management block that
allows software and accelerators on the datapath to enqueue and dequeue
frames in order to communicate.
bus/dpaa: add layer for interrupt emulation using pthread
An interrupt manager is implemented by emulating over pthreads.
Handlers are registered by QBMAN layer for being notified about
any interrupt request from DPAA blocks in userspace.
Coverity reports check_after_deref:
Null-checking rq suggests that it may be null, but it

This patch removes NULL checking of "rq" from function
vmxnet3_dev_rx_queue_reset as it is already checked against NULL
one level up the callstack (function vmxnet3_dev_clear_queues).

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.
