<P><FONT SIZE=2>Hi,</FONT>
<BR><FONT SIZE=2>The osm_vendor_mlx_ts_anafa.c is very close to what you need, it just contain some hard-coded values (e.g. one port) that will not suite Tavor.</FONT></P>
<P><FONT SIZE=2>But you can easily take it and change it in the way that will eliminate the need for any VAPI call in OpenSM.</FONT>
</P>
<P><FONT SIZE=2>Of course you need to close the API for user space but this should be done in any case.</FONT>

<BR><FONT SIZE=2>> Tom> I have only just began to look into it. What is it going to</FONT>

<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> I think all the VAPI calls from osm_vendor_XXX.[ch] need to be</FONT>
<BR><FONT SIZE=2>> removed. It's not clear to me how close osm_vendor_mlx_ts_anafa.c is</FONT>
<BR><FONT SIZE=2>> to what we would need.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> It's definitely possible on top of the current mthca driver, since</FONT>
<BR><FONT SIZE=2>> sending and receiving MADs is all that is required.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> In any case all this MAD/GSI discussion is going to lead to a change</FONT>
<BR><FONT SIZE=2>> in the userspace interface (not to mention the requirement of being</FONT>
