OPDL ring is the core infrastructure of OPDL PMD. OPDL ring library
provide the core data structure and core helper function set. The Ring
implements a single ring multi-port/stage pipelined packet distribution
mechanism. This mechanism has the following characteristics:
• No multiple queue cost, therefore, latency is significant reduced.
• Fixed dependencies between queue/ports is more suitable for complex.
fixed pipelines of stateless packet processing (static pipeline).
• Has decentralized distribution (no scheduling core).
• Packets remain in order (no reorder core(s)).
* Update build system to enable compilation.

Without this patch, the number of queues per i40e VF is set to 4
by CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VF=4 in config/common_base.
It is a fixed value determined at compile time and can't be changed
at run time.
With this patch, the number of queues per i40e VF can be determined
at run time. For example, if the PCI address of an i40e PF is
aaaa:bb.cc, with the EAL parameter -w aaaa:bb.cc,queue-num-per-vf=8,
the number of queues per VF created from this PF is set to 8.
If there is no "queue-num-per-vf" setting in EAL parameters, it uses
the default value of 4. And if the value after the "queue-num-per-vf"
is invalid, it will also use the default value. The valid values can
be 1, 2, 4, 8, or 16.

Generic Segmentation Offload (GSO) is a SW technique to split large
packets into small ones. Akin to TSO, GSO enables applications to
operate on large packets, thus reducing per-packet processing overhead.
To enable more flexibility to applications, DPDK GSO is implemented
as a standalone library. Applications explicitly use the GSO library
to segment packets. To segment a packet requires two steps. The first
is to set proper flags to mbuf->ol_flags, where the flags are the same
as that of TSO. The second is to call the segmentation API,
rte_gso_segment(). This patch introduces the GSO API framework to DPDK.
rte_gso_segment() splits an input packet into small ones in each
invocation. The GSO library refers to these small packets generated
by rte_gso_segment() as GSO segments. Each of the newly-created GSO
segments is organized as a two-segment MBUF, where the first segment is a
standard MBUF, which stores a copy of packet header, and the second is an
indirect MBUF which points to a section of data in the input packet.
rte_gso_segment() reduces the refcnt of the input packet by 1. Therefore,
when all GSO segments are freed, the input packet is freed automatically.
Additionally, since each GSO segment has multiple MBUFs (i.e. 2 MBUFs),
the driver of the interface which the GSO segments are sent to should
support to transmit multi-segment packets.
The GSO framework clears the PKT_TX_TCP_SEG flag for both the input
packet, and all produced GSO segments in the event of success, since
segmentation in hardware is no longer required at that point.

Currently, enabling assertion have to set CONFIG_RTE_LOG_LEVEL to
RTE_LOG_DEBUG. CONFIG_RTE_LOG_LEVEL is the default log level of control
path, RTE_LOG_DP_LEVEL is the log level of data path. It's a little bit
hard to understand literally that assertion is decided by control path
LOG_LEVEL, especially assertion used on data path.
On the other hand, DPDK need an assertion enabling switch w/o impacting
log output level, assuming "--log-level" not specified.
Assertion is an important API to balance DPDK high performance and
robustness. To promote assertion usage, it's valuable to unhide
assertion out of COFNIG_RTE_LOG_LEVEL.
In one word, log is log, assertion is assertion, debug is hot pot :)
Rationale of this patch is to introduce an dedicate switch of
assertion: RTE_ENABLE_ASSERT
