In QNX7.0 and 7.1, the network arch is base on io-pkt and we can implement our lsm pf module to io-pkt to accept or drop
 network packets.
Currently, we would like to migrate to QNX 7.1/8.0 io-sock arch,  but from the development doc, I can't find the way or 
any interface description about how to load my lsm pf module to io-sock.
Is there anyone know how to do this? 
Thanks.
