>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
>module that is registered as
>Netfilter Hook. I tried to make use of NF_QUEUE but found that only
>one call back function per
>protocol family (PF) is provided and already some module (probably
>NET_LINK socket interface)
>is making use of it for PF_INET. Is there any way to use NF_QUEUE
>facility without disturbing
>NET_LINK ? why per hook registration of call back function of
>NF_QUEUE is not provided?
>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
>hooks can get pkts?
>any help is highly appreciated.
>Thanks
