A bit of digging narrowed it down the fact that we were asking the PF to associate all causes with ITR 0 as we weren't populating the itr_idx values for either Rx or Tx. To correct it I have added the configuration for these values to this patch. In addition I did some minor clean-up to just add a local pointer for the vector map instead of dereferencing it based off of the index repeatedly. In my opinion this makes the resultant code a bit more readable and saves us a few characters.
