From 0e44eb209343663ad7041ebf9f5d4c393bd89ae9 Mon Sep 17 00:00:00 2001 From: Shahar Levi Date: Mon, 16 May 2011 15:35:30 +0300 Subject: [PATCH] wl12xx: Enable beacon early termination in 2.4GHz band only Beacon early termination doesn't help much in the 5GHz band and masks channel switch IE Beacons. Thus, change the code to use BET only in 2.4GHz.
