From aa833c4b1a928b8d3c4fcc2faaa0d6b81ea02b56 Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Mon, 21 Feb 2011 10:57:10 -0800 Subject: iwlwifi: split the drivers for agn and legacy devices 3945/4965 Intel WiFi devices 3945 and 4965 now have their own driver in the folder drivers/net/wireless/iwlegacy Add support to build these drivers independently of the driver for AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko, and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko contains code shared between both devices. The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3 ABGN device.
