From 5404643139c16e56d31a6ebd09cfa6db1eb03a36 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 20 Oct 2010 15:15:52 +0300 Subject: [PATCH] wl1271: exit ELP mode when setting enabled rates in tx This bug was being triggered by a call to acx_rate_policies in tx_work without calling ps_elp_wakeup first. If we have full PSM enabled, this happens rather often, immediately after association.
