[GS] OpenIB goal is to provide Linux and Windows stack.

[GS] I would not refer to it as a port. This is another code base. OpenIB
host 2 independent repositories - Linux and Windows. Of course there might
be code sharing.

[GS] Windows drivers are already ready to download. I did not check the 
general OpenIB web site lately, but it should refer to Linux and Windows 
on the same manner. I will check this out. Thanks.

[GS] There is no meaning of Gen1 for Windows since there are no plans for
Gen2. We have already created a release and will continue to have future
releases. Windows is part of OpenIB output and the code is availble under
one license only - BSD.

[GS] There is no relationship to Linux. The Windows repository was created
due
to a need for the market. Windows repository contain ULPs that are also part
of the Linux repository but also ULPs that are Windows only. The work on the

Windows part is driven by Windows users, as the new ULPs that are being
added
and will be in the future.
