Honestly, I thought that patch 14 was too hard to review and did too
many things, but this one is kind of ridiculous.

-	p->rfa_txpowertrackingindex--;
+	(*rfa_pti)--;

The new version is fewer characters but it's way more complicated to
think about.  Just rename rfa_txpowertrackingindex to something
reasonable.  It's a stupid name, because it_hasninegazillionwordsinit
and it's too long.

"rfa_pti_r" is a terrible name as well.   it_also_hngwit_for_realz.

I'm not going to review the rest of this patch.

dan carpenter
