Ravi,
   Did you try with the 'krping' (kernel module) utility ? This is the same as 
'rping' but it's a kernel module instead of a user space application.
Also hope you are using the latest stack.
Also enable debugging for the Ammasso driver (modprobe rdma_krping debug=3) and 
send us the dmesg output.

Thanks,
Pradipta Kumar
