NTDEV: NDIS Miniport Driver ...

NTDEV

hi all,
I have a requirement that my NDIS Miniport driver requires to send a signal to a upper layer driver (Intermediate Driver In NT).
Can i Send some information from the NDIS Miniport Driver to a Intermediate Driver ??? if yes then how is it possible??
I do not want to “Query” my Miniport using a timer because that is a performance degradation and un-necessary processing.

any clues???

Perhaps you can use a private OID to exchange a “jump table” (like NDIS
characteristics tables). Then call functions using the jump table to
“signal” your other driver.

Good luck,

I use the NdisMIndicateStatus() function to talk to my protocol driver. It
appears to work fine. I just defined a “status” that both the drivers
understood. There is a small possiblity that a generic protocol would
misunderstand the status indication but the rule is that if a protocol
doesn’t recognize a status, it should ignore it.
