Currently, when use 'flow' command to create a rule with following
invalid RSS type combination, it can be created successfully.

Invalid RSS combinations list:
 - ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP

vhost: enhance async enqueue for small packets

Async enqueue offloads large copies to DMA devices, and small copies

enqueue completed packets by rte_vhost_poll_enqueue_completed(), even
if they are completed by the CPU when rte_vhost_submit_enqueue_burst()

number of jobs, each with a different segment of a file to parse.  This
commit adds support for multiple QPs assignments. All QPs will be
assigned the same number of jobs, with the same segments of file to
parse. It will enable comparing functionality with different numbers of
QPs. All queues are managed on one core with one thread. This commit
focuses on changing routines API to support multi QPs, mainly, QP scalar
variables are replaced by per-QP struct instance.  The enqueue/dequeue
operations are interleaved as follows:
 enqueue(QP #1)
 enqueue(QP #2)
 ...
 enqueue(QP #n)
 dequeue(QP #1)
 dequeue(QP #2)
 ...
 dequeue(QP #n)

A new parameter 'nb_qps' was added to configure the number of QPs:
 --nb_qps <num of qps>.
If not configured, nb_qps is set to 1 by default.

eal: add generic thread-local-storage functions

Add support for TLS functionality in EAL.

The following functions are added:
rte_thread_tls_key_create - create a TLS data key.
rte_thread_tls_key_delete - delete a TLS data key.
rte_thread_tls_value_set - set value bound to the TLS key
rte_thread_tls_value_get - get value bound to the TLS key

TLS key is defined by the new type rte_tls_key.

The API allocates the thread local storage (TLS) key.
Any thread of the process can subsequently use this key
to store and retrieve values that are local to the thread.

Those functions are added in addition to TLS capability
in rte_per_lcore.h to allow abstraction of the pthread
layer for all operating systems.

Windows implementation is under librte_eal/windows and
implemented using WIN32 API for Windows only.

Unix implementation is under librte_eal/unix and
