(Is there an existing test program or...?) There are programs, yes. I used (rather old) netperf-2.2pl4 (I can send it to you) running under perf (provided by the Poky rootfs). The details running netperf on target are in the patch description #2; on host you just run netserver from that same testsuite. The current netperf is maintained by HP on github but I was unable to figure out how to build it quickly enough... :-) > Also, can this be tested under QEMU's r2 board emulation? I have no idea, sorry. > Rob MBR, Sergei
