From 52e6b85fe07ed1d2b5c76fd42ce1d77f1a190c72 Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Tue, 18 Jan 2011 08:58:48 -0800 Subject: iwlagn: add IQ inversion support for 2000 series devices The I/Q swapping is extremely important and should be dealt with extra care. It will affects OFDM and CCK differently. For 6000/6005/6030 series devices, the I/Q were swapped, and for 2000 series devices, it is in non-swapped status (but its swapped with respected to 6000/6005/6030). so the CSR_GP_DRIVER_REG_BIT_RADIO_IQ_INVER register need to be set to support the correct behavior.
