For multi-segment packets, the Tx checksum offload doesn't work
except the last segment, because other segments don't enable HW
checksum offload successfully.

The purpose of the dispatcher library is to decouple different parts
of an eventdev-based application (e.g., processing pipeline stages),
sharing the same underlying event device.
The dispatcher replaces the conditional logic (often, a switch
statement) that typically follows an event device deque
The purpose of the dispatcher library is to help reduce coupling in an
Eventdev-based DPDK application.
In addition, the dispatcher also provides a convenient and flexible
way for the application to use service cores for application-level
processing.

In some really specific cases, it may be needed to get a detailed

achieve better performance, or for matters that concern only them.
Those information are highly arch-specific and require a specific API.
Introduce a set of fun
Rather than have every driver implement their own set of cpuid() ugly
stuff, provide an abstracted (gcc/clang vs MSVC) API for querying about
x86 processor details.

specific API has been preferred. If other arches have
