Hi,

I am using 6.3.2 and my Ethernet controller is a 10/100 Mbit Fast Ethernet. I don't know much about Ethernet/Networking 
stack in QNX expect using few basic commands like io-net, ifconfig, dhcp.client, etc.

I noticed that whenever I transfer data to/from my system (Vortex SoC 800 MHz) the CPU usage goes up to 100% and I get 
terrible speeds (as compared to running the system over Linux). I suspect that my QNX Ethernet driver might not be using
 the full DMA capabilities. How can I check that? I used nicinfo utility but did not see any DMA related information in 
the output.

Thanks.
