>Hi All,
>I'm using Linux RedHat 9  kernel version 2.4.20-8
>I want to do some asynchronous processing of packets in my kernel

>NET_LINK ? why per hook registration of call back function of

>How to proceed if someone had to do async processing of packets so 
>that pkts can be queued to crypto hardware processing unit and can 
>be safely reinjected back into kernel later so that other registered

>any help is highly appreciated.
