[dpdk-dev] [PATCH V1 1/1] jobstats: added function abort for job

[Marcin Kerlin]

This patch adds new function rte_jobstats_abort. It marks *job* as finished
and time of this work will be add to management time instead of execution time. 
This function should be used instead of rte_jobstats_finish if condition occure,
condition is defined by the application for example when receiving n>0 packets.
