segment limit is always zero?<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV dir=ltr>When I call dat_ep_query(), the max IOV segments for RDMA
read/write always is returned as zero. I tried it on a couple different
adapters (Mellanox 26428 and 25204). Does the value zero mean something
else, like "unlimited"? I'm using DAT 2.0 and the code looks like this:<SPAN

<DIV dir=ltr><SPAN class=000412616-29072008><FONT face=Arial color=#0000ff

socket cm provider. I will fix this for OFED
