Virtual network adapters

Hi,
I have written a virtual network adapter/Virtual miniort
driver(NDIS). I want to send the data i receive in my virtual adapter's
MiniportSend funcion across network using a network device.
Inorder to do that, the packet i have received in virtual miniport driver's
MiniportSend has to be passed to MiniportSend of miniport driver. NDIS
intermediate drivers passes the packet to the miniport driver using NdisSend.
Since the driver i have written is not an intermediate driver,NdisSend
function can not be used to send the packet to a miniport driver. NdisSend
function requires the binding handle which a virtual miniport driver can not
have. Only NDIS intermediate driver can get a binding handle which it can use
in NdisSend.
Could you let me know how can i pass the packet to the MiniportSend
of miniport driver from my MiniportSend of virtual miniport driver?
Thanks & Regards,
Senthil

Somebody correct me if i am wrong but i read somewhere that one can expose a
virtual adapter from an IM driver,so if an IM binds to all miniports and
protocols ,it can get all binding handes and can use them to send packets
directed for one adapter to be sent to another adapter ?could it be a
solution here ?

Hi Gupta,
Thanks for the prompt reply. What i have developed is a
virtual network driver not an intermediate driver. so my driver will not have
any binding handle which i can use to send the data.
So my virtual network driver is like any other network driver. The
packets received by virtual network driver has to be sent to a network driver
so that it can reach the destination.
Thanks,
Senthil

Such a driver must be a MUX-style intermediate.

Hi Maxim,
My driver is like netvmini sample of DDK. I want to pass
packets to the destination using a network device.
Thanks
Senthil

This means you need a MUX driver.
