I was using Mellanox OFED 2.0-3.0.0 for Ubuntu, and under the SOURCES directory I had a file "opensm_4.0.5.MLNX20130808.c2b40b1.orig.tar.gz".
I just updated my Ubuntu 12.04 machines to the latest Mellanox OFED version (2.3-2.0.0) but I cannot find the source code of OpenSM anymore.
Where can I get a copy of the OpenSM source code for the latest version?
