| |
2.6.35-stable review patch. If anyone has any objections, please let us know.
------------------
From: Luis R. Rodriguez <lrodriguez@atheros.com>
commit 803288e61e346ba367373bc7d5eeb6e11c81a33c upstream.
The EEPROM is compressed on AR9003, upon decompression the wrong upper limit was being used for the block which prevented the 5 GHz CTL indexes from being used, which are stored towards the end of the EEPROM block. This fix allows the actual intended regulatory limits to be used on AR9003 hardware.
