Hi Dave,

Please don't apply this patch to net-next. The other 4 patches in this
series should be fine without it. If this patch is applied to net-next
it means that most/all of the other fcoe features (that will go through
linux-scsi) become dependent on this patch.

I was hoping to push the other fcoe features as-is and then push this
patch through linux-scsi after the other 4 patches in this series had
been merged by you.

Thanks, //Rob
