From e832837bbb91ae8610fa0a0f3d243d42823ec815 Mon Sep 17 00:00:00 2001 From: Victor Goldenshtein Date: Mon, 14 May 2012 13:55:47 +0300 Subject: [PATCH] wlcore: don't enable BET for high basic rates The beacon early termination is not relevant for high basic rates, which doesn't contribute anything to the PS and only adds unnecessary FW work. Enable BET only if the basic rate is less than 9 Mbps.
