<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My name is David and I’m a software engineer.
Currently I’m interested in APIs that bypass the Windows (kernel) TCP/IP
stack, and I’ve been told that OFED is the answer to my prayers. My
company already bought Mellanox NIC (Ethernet), so now is time to change our
software. I’ve been checking the openfabrics webpage, and
wiki.openfabrics.org, although we can find some documentation, I don’t
know where to start. Is there anyone that can point me to the right direction?
Like: Which API’s for windows to use for Ethernet NICS? Is there documentation
to that particular API? Can I find API’s for c# and/or c++?? Any other
information will be much appreciated.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks a lot<o:p></o:p></p>
