H A Dnapi.rst226 可以从 ``epoll_wait`` 调用直接触发数据包处理。为了使用此功能，用户应用程序必须确保添加到
239 范围的设置，将导致所有基于 epoll 的应用程序在调用 epoll_wait 时忙轮询。这可能不是理想
290 只要应用程序对 epoll_wait 的调用成功获取事件，内核就会推迟 IRQ 挂起定时器。如果
301 为覆盖用户应用程序调用 epoll_wait 处理数据所需的时间，需注意的是，应用程
302 序可通过在调用 epoll_wait 时设置 ``max_events`` 来控制获取的数据量。
312 如上所述，只要后续对 epoll_wait 的调用向用户空间返回事件，``irq-suspend-timeout``
315 一旦 epoll_wait 的调用没有找到任何事件，IRQ 挂起会被自动禁用，并且 ``gro_flush_timeout``

H A Dnapi.rst274 ``epoll_wait``. In order to use this feature, a user application must ensure
292 epoll-based applications to busy poll when they call epoll_wait. This may

374 they retrieve by setting ``max_events`` when calling epoll_wait.
