My wireless access point suddenly started logging tons of messages like these:

0x80)

It's been going on for many hours and then suddenly stopped.
Not sure what happened but suspect that maybe a specific station appeared and
then disappeared.
There is comment in the code indicating that this must be a driver bug:
/* Warn if this function is called for 11n rates; it should not be! */
I captured a stack trace of a call:

Not a huge issue but I didn't like that it spammed logs so much.
So, I'd like to get this fixed.
Does anyone have an idea where the problem might be?
Thanks!
