Re: ath(4) issues?

hi!

No. It's a side effect of how ath_rate_sample works. The TL;DR is:

* ath_rate_sample uses a fixed set of rates for each attempt - so say you
want to transmit at 54MBit OFDM, the second/third/fourth slower rates are
in a fixed table;
* net80211 negotiates which rates are acceptable to the hostap;
* a lot of hostaps these days are increasingly disabling doing the lower
OFDM/CCK rates so slower clients don't tie up so much air;
* .. but they'll still RECEIVE and ACK those frames, so:
* + you'll fail say, 54mbit
* + and 48mbit
* + then try something like 12mbit on the third attept, which the hostap
didn't negotiate with you; and
* + it ACKs it, cause it still receives it fine; then
* + ath_rate_sample complains that it got a completion for a rate it's not
supposed to use.

They're harmless. You can comment it out for now; I really need to fix
ath_rate_sample to use a dynamic table rather than the array of static
tables..
