Hi,
   In io-pkt implementation , when does the iface_hook gets invoked. I mount the filter and I see the input hook and 
output hook get invoked as a when packets come in and go out of stack. But I am unable to see the message I have put in 
when the iface_hook is added.

If I am not wrong this gets invoked when the filter module attaches to the driver ethernet driver module.

I do not see this happening.

I am just executing the sample code. 

Can anyone please put in the right direction?

Regards
Vinod
