A new interrupt type, RTE_INTR_HANDLE_VDEV, is added to support lsc and rxq interrupt for vdev. For lsc interrupt, except from original EPOLLIN events, we also listen for socket peer closed connection event (EPOLLRDHUP and EPOLLHUP). For rxq interrupt, add a precondition to avoid invoking any vfio and uio code. For intr_handle initialization, let each vdev driver to do that. Signed-off-by: Jianfeng Tan <jianfeng.tan@intel.com>
