[ofw] some WinOF questions

[Tzachi Dar]

Hi Diego,

SDP is indeed not part of WinOF. It is a component that is supplied by
Mellanox (and some of it's partners) only. If you want to try it than
the simplest way is to install WinIB 1.3. If for some reason you want to
stick to the OFED libraries than I'll have to provide you with the SDP
binaries that much that version. (actually due to some bug in the
interoperability, I'll probably have to give you a fix in any case).

Please also note that:
1) Windows SDP was tested against OFED 1.2 and not 1.1 (as far as I can
remember there were problems that were fixed in 1.2)
2) You can use Iperf as a benchmark that works both on Linux and on
windows. From my experiments with this tool, SDP should give BW that is
at least 3 times higher than IPOIB.

Thanks
Tzachi
