[v4 0/3] ethdev: introduce protocol type based header split

[wenxuanx.wu at intel.com]

From: Xuan Ding <xuan.ding at intel.com>

Header split consists of splitting a received packet into two separate
regions based on the packet content. It is useful in some scenarios,
such as GPU acceleration. The splitting will help to enable true zero
copy and hence improve the performance significantly.

This patchset extends the current buffer split to support protocol based
header split. When Rx queue is configured with header split feature,
packets received will be directly splitted into two different mempools.

v3->v4:
* Use RTE_ETH_RX_HEADER_SPLIT_NONE instead of 0.

v2->v3:
* Fix a PMD bug.
* Add rx queue header split check.
* Revise the log and doc.

v1->v2:
* Add support for all header split protocol types.
