So the driver supports CCMP..

And accepts a connection that uses CCMP..

And connects to the requested AP..

But then rejects a command to set the CCMP key for the AP with which
there is an association and using an error code that would imply the STA
entry for that AP is not present.

I'm not familiar with the driver used here, but someone would need to
take a look at what it is doing in this type of case to figure out what
needs fixing.
