[dpdk-dev] [PATCH] eventdev: update event port link and unlink callbacks

[Nipun Gupta <nipun.gupta@nxp.com>]

Added a pointer to the rte_eventdev type in the event port
link and unlink callbacks. This device shall be used by some
of the event drivers to fetch queue related information.

Also, update the skeleton eventdev driver with corresponding changes.
