This patch was crafted long time ago to work around a key cache
corruption problem on ath9k chipsets.

The workaround consists in periodically triggering a worker that
uploads all the keys to the HW cache. The worker is triggered also
when the vif detects 21 undecryptable packets.


This patch is based on top compat-wireless-2015-10-26.


I was asked to release this code to the public and, since it is
GPL, I am now doing it.

GPL? AFAICS ath9k is under ISC. I'm not sure what you mean with the
sentence above, but it's possible to interpret it so that this patch is
not under ISC license, which is problematic.
