Normally a net driver doesn't use, it is instead used. If you are thinking about net performances you can launch on your board (ip addr = 10.39.10.183): iperf -s And from a PC: iperf -c 10.39.10.183 -w 64k (64k means 128k, due to an iperf known issue) You will need to reach the following performances, if dm365 is your case: http://processors.wiki.ti.com/index.php/DaVinci_PSP_03.01_GA_%28r37%29_Release_Notes#Performance_-_DM365_EVM The only "problem" is that the packets, arriving to dm365 board, are going to be discarded and I don't know if they are copied to the user-space. If you can do: strace iperf -s and check if the copy is done you will have the answer you need. bye, Raffaele _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
