<p class=MsoNormal> <o:p></o:p></p>

<p class=MsoNormal>Hal is correct, IBTA allows LMC to vary per port.  There are
existing configurations where the QLogic SM can configure a different LMC value
for certain types of nodes in the fabric.  All of which need to be able to
participate in IPoIB.<span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
