<div>Hi Arlin,</div>
<div><br>
</div>
<div style="direction: ltr;">I attended the first 30mins of the meeting. Sorry I had to drop off before the end to go to another meeting. I mostly agree with others that having a OFED release with just bug fixes isn't that helpful. It's better to have a fully
featured one. Having said that we are happy to do backports to either one.</div>
<div><br>
</div>
<div style="direction: ltr;">We right now have just enough resources (me) to do backporting. I'll have to check internally if some other folks might volunteer if we want to stick with the full version of OFED.</div>
<div><br>
</div>
<div style="direction: ltr;">- Adit</div>
