Hi, SDP does not keep packet size statistics, but could if people want. Active connection info can be found in /proc/net/sdp, and the counters (and parameters) we do keep are in /sys/module/ib_sdp.
There are a couple debug options that can be enabled. If you want to see per-frame detail, then you need to build with CONFIG_INFINIBAND_SDP_DEBUG_DATA defined and enable with /sys/module/ib_sdp/<hmm>/data_debug_leve=1. Then run something small and use dmesg to get the details. You can also enable some debug info on the normal build by setting debug_level=1 in the /sys/module/ib_sdp tree.

OK, thanks for the info, I will check to see if they still suspect that the NO_DELAY does not function as it should and let you know. Is there a way to see packet size statistics for SDP without an IB analyzer, do you expose some sysfs based statistics etc? Or. _______________________________________________ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
