[PATCH v1 2/2] eventdev: add support for enqueue reorder

[Abdullah Sevincer <abdullah.sevincer@intel.com>]

This commit adds support flag to enable enqueue reorder
feature.

When this flag is enabled in the port configuration PMD
restores dequeue order on enqueue if applications happen to
change it.
