Thanks and Regards

Check out the networking repo and follow the build
instructions here:

http://community.qnx.com/sf/wiki/do/viewPage/projects.networking/wiki/Source_Guide

Once done you'll have a bunch of devnp-* under your
stage under lib/dll.

If it's already built the easiest way is:

# io-pkt -d /fullpath/to/your/devnp-foo.so

If you check out the repo you'll have several examples.
You can either make a new dir under sys/dev_qnx or
modify the sample driver.  Once that's done a straight
'make' will build it.

It there's already an io-pkt running the
previous command will in effect overlay
the socket handling of the previous.  If
you want to run two io-pkt instances look
at the 'prefix' option to the tcpip proticol
in the io-pkt docs:

# io-pkt -d /fullpath/to/your/devn-foo.so -ptcpip prefix=/alt
# SOCK=/alt ifconfig

There's not enough info in that problem description.
The file you attached is the sample driver from the
networking project.  I suggest you download the entire
project and follow the source guide:
