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
