[EZ] It is available (the code was part of IBAL but needed some fixes etc).

[EZ] The different implementations are already included in the OpenSM code
on the OpenIB trunk. They are not named Win/Linux but IBAL, TS. I propose we
perform some restructuring where each "vendor" has its own package and all
of them are actually made into the same "lib" name. Such that for OpenSM
build it should not make any difference which vendor it is linked with.

[EZ] I mean using topology file to map discovered topology to specified
topology and thus enable the use of the user given names for the various
systems (instead of guids).

[EZ] The MAD layer provides scripting interface for sending receiving mads
of the various classes.
The analysis layers perform topology matching, LFT traversals, credit loop
analysis, MFT connectivity checks, routing hops histograms, etc.

[EZ] The idea is to move the current tools into OpenIB and use OpenIB as the
development environment. This includes OpenSM and the MAD layers.
All should be autotools.
