forgive my ignorance, but what should i do to be a “child driver of the NIC”?, or what type of driver can be regarded as a “child driver of the NIC”?
also, what dose “non power pagable group” mean, i googled this phrase, but find nothing. what’s it?
would you like to explain your last reply more detailedly, thanks.

There is no way to express this dependency unless you are a child driver
of the NIC. You can send the NIC a usage notification which will put
you both into the non power pagable group, but there is no ordering
guarantee within that group…but that may be enough. By both being non
power pagable, you are powered down after the file systems have flushed
which means you will not see any FS I/O or paging I/O. Then you can
power down your devices (if that even applies for a remote device) when
either your NIC or your storage driver powers down first (you will have
to use NDIS pnp notification callbacks or roll your own). You would
have the same problem if the NIC was disabled at runtime as well and
this solution solves that.
