You can use either method, but regarding method 1, check the usage 
messages for the ncm driver as it provides instructions on how to load 
it when you start io-pkt:

# use /lib/dll/devnp-ncm.so

Also check the output of sloginfo after you try to load the driver as it 
will indicate initialization errors.

I used following command and it worked - 
# io-pkt-v4-hc -d ncm pnp verbose &
or you can specify path i.e. #io-pkt-v4-hc -d ncm pnp path=/lib/dll/devnp-ncm.so verbose &
But make sure the sequence. It matters.
If you give "pnp" after "path" then it will not work.
