Still working on the HW key/encryption/decryption support under the
`LKPI_80211_HW_CRYPTO` block.


   - This week I was still testing the key setup paths to see any clue that
   leads to HW crypto offload malfunction. But as I was stuck with some dead
   ends, I took one day off last Friday to refresh my jammed brain.


   1. I dumped more key setup traces with key contents. But all these
      traces confirm the key setup progress in firmware (Linux vs. FreeBSD) is
      correct.
      2. Also the way how a ucast key is used in the TX path is verified
      again.

Today, adrian@ and I took several hours debugging the code and analyzing
different code paths. Also there is email discussion with Johannes Berg
that adrian@ helped to reach out with.
