FILTER_ACQUIRE_LOCK(&pFilter->Lock, DispatchLevel);
if (pFilter->State != FilterRunning)
{
FILTER_RELEASE_LOCK(&pFilter->Lock, DispatchLevel);
if (NDIS_TEST_RECEIVE_CAN_PEND(ReceiveFlags))
{
ReturnFlags = 0;
if (NDIS_TEST_RECEIVE_AT_DISPATCH_LEVEL(ReceiveFlags))
{
NDIS_SET_RETURN_FLAG(ReturnFlags, NDIS_RETURN_FLAGS_DISPATCH_LEVEL);
}
NdisFReturnNetBufferLists(pFilter->FilterHandle, NetBufferLists, ReturnFlags); } break;
}
FILTER_RELEASE_LOCK(&pFilter->Lock, DispatchLevel);
这样应该在驱动暂停时停止了接收和发送新的数据。但是如何等待正在发送和接收的数据完成呢？我在FilterPause添加了：
if (pFilter->OutstandingRcvs > 0 || pFilter->OutstandingSends > 0)
{
NdisMSleep(5000000);
}
但是不起作用，没有延迟等待，NdisMSleep一下就过去了，KeWaitForSingleObject 也是一样的状况，这是为什么呢？是因为IRQL>=DISPATCH_LEVEL吗？那我该如何在FilterPause等待已发送和接收的数据完成呢？如何设定延迟呢？
