2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Luis R. Rodriguez <lrodriguez@atheros.com>

commit 5ffaf8a361b4c9025963959a744f21d8173c7669 upstream.

Some single chip family devices are sold in the market with
802.11n bonded out, these have no hardware capability for
802.11n but ath9k can still support them. These are called
AR2427.
