This patch add support to use select call with qman portal fd for timeout based dequeue request for eventdev. If there is a event available qman portal fd will be set and the function will be awakened. If no event is available, it will only wait till the given timeout value. In case of interrupt the timeout ticks are used as usecs. Signed-off-by: Hemant Agrawal <hemant.agrawal@nxp.com>
