From: Vidhya Govindan Date: Tue, 17 Nov 2009 16:49:23 +0000 (+0200) Subject: wl1251: Increase the beacon loss timeout value and handle regain event X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=33d51facad8360cb9c55fd696431e2a477f16cc1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git wl1251: Increase the beacon loss timeout value and handle regain event This patch increases the number of beacons to be missed before generating SYNC TIMEOUT event. It increases the beacon timeout period to 500 microseconds, which gives enough time for the firmware to receive probe response or beacon. Also handled the regain event from firmware once it receives a probe response or beacon.
