I believe we are a rather friendly bunch (but who does not have that
self image) and will put observed data before theory any day ;)

Ihink I read in the openwrt forum people use the serial/jtag port for
such things, but the memory is dim and the thread by now has reached like 900
pages or so...

Cool! I note it seems you are running an older flent version (or maybe
even before the big rename, so netperf-wrapper). I think current flent includes
enough improvements to merit a switch; I especially like
“[email protected]” option to collect some data from the DUT
automatically and save these into the output file, making it easy to answer a
few question about the configuration used a few days/hours after the fact).
Also I want to note that if you shape ethernet you should use the link
layer adaptation built into sqm (configurable via the GUI): Select Ethernet
with overhead and specify the overhead to be: 24 Bytes (ethernet pre-amble &
interframe gap & FCS, Linux will have already accounted for MACs & frame type
14 bytes, you may need to add vlan tag (4 additional bytes)).

Ah, that got me confused, I see the new files just fine.
