Hello,
        I want to know if the shim driver which is used for backward compatibility to use with io-net NIC driver from 
QNX6.4 under io-pkt, is workable even for the filter/converter module. 

I am porting the filter module from io-net to io-pkt. If this shim driver works for filter/converter module then I can 
try using the shim driver.

I have browsed through the forum and internet for porting related info but was able to find an example of using the pfil
 hook to access mbuf  at

http://www.qnx.com/developers/docs/6.4.1/io-pkt_en/user_guide/migrating.html

Can anyone please give me some more input on using mbuf so that I can straight away convert to iov type or point me to 
some example in BSD implementation, which at least reduces my effort in understanding.

Regards
Vinod
