I'll just repeat that the key move to get this driver out of staging is
to get away from the WEXT interface to CFG80211. Otherwise no chance
that wireless maintainers will even look at it. This is a huge change
but once it is done, features like Michael MIC come with it for free
(from what I recall, I am not a wireless expert myself).

Without the CFG80211 conversion, replacing the Michael custom
implementation with the in-kernel one makes the driver a tad better and
is good exercise. However, it will sadly not help to get the driver out
of staging.

But if you want a clean WEXT driver first, this is a step in the right
direction.
