Re: [dpdk-dev] [PATCH V16 1/4] eal: add device event handle in interrupt thread

[Tan, Jianfeng]

Hi,

Add new interrupt handle type of RTE_INTR_HANDLE_DEV_EVENT, for
device event interrupt monitor.

A simple search of RTE_INTR_HANDLE_ALARM, we can see that we still need 
to update rte_intr_enable()/rte_intr_disable(), and test_interrupt_init().

Thanks,
Jianfeng
