I want and need to program the key into the device so that it can do the
encryption for transmit.  But, I need software to do full decryption on
receive.

That is the only way I could get ath10k to do any sort of software crypt,
and in fact, that is the most efficient way to get the features I need
so I might try getting ath9k to support the same mode some day...

I'll be posting ath10k patches to use this soon, but the dark magic
is down in the firmware in this case.

Thanks,
Ben
