I'm sorry.  I really hate to do this to you...  But the right thing here
is to use net_dbg_ratelimited() but get rid of the if (net_ratelimit())
check.  So it looks like this:

	if (!(keyidx & (1 << 5))) {
		net_dbg_ratelimited(skb->dev,
				    "CCMP: received packet without ExtIV flag from %pM\n",
				    hdr->addr2);
	}

Sorry again, when I looked at it before I just replied what my fast
thinking lizard brain said instead of taking time to look at what I was
saying.
