关于多个中间层驱动安装安装顺序和绑定顺序的问题，请高手指教

1、建议合2为1
2、驱动应该存在优先级，具体我也不清楚；）

我也没有处理过，不过理论上可以确定加载的顺序吧，研究一下inf文件

try

INetCfgComponentBindings::MoveBefore()
INetCfgComponentBindings::MoveAfter()

DDK的netcfg example演示了怎么使用INetCfgComponent以及其它一些COM接口，并且可以改装一下它来安装IMD

ddk里面关于inf的说明部分里面讲了passthru的3个层次。

The FilterClass value of a filter intermediate driver determines its order in a stack of filters. Filter intermediate drivers must define the FilterClass key. The class of the driver can be one of the values in the following table:

Value DescriptionMeaning
scheduler
 Packet-scheduling filter service. This class of filter intermediate driver is the highest driver in a stack. A packet scheduler detects the 802.1p priority classification given to packets by QoS-signaling components, and sends those packets according to their priority levels to underlying drivers.
 
loadbalance
Load-balancing filter service. This class of filter intermediate driver exists between packet-scheduling and fail-over drivers. A load balancing filter service balances its workload of packet transfers by distributing the workload over its bundle of underlying miniport instances.
 
failover
Fail-over filter service. This class of filter intermediate driver is the lowest driver in a stack. That is, no other drivers that belong to other classes, if installed, can be between this driver's virtual miniport and the adapter being filtered.  

hoho，如果装的2个都是failover呢？
 :D

ddk里面没有说装两个会有什么后果。

我装了三个failover，好像都工作的挺正常的，
