Hi, Nick

The problem of ath5k right seems to be that: '
If CCMP HW encryption is enabled, HW encryption for unicast data frame
and SW encryption for unicast management frame are possible for TX.
But for RX, both the unicast data frame and unicast management frame
are decrypted by the HW instead of doing only SW decryption for
unicast management frame.

With the help of PCU DIAG register, possible to separate this?
