From 40b359c61dc496508b77d1242726e40238e62128 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Thu, 1 Apr 2010 11:38:19 +0300 Subject: [PATCH] wl1271: Fix keep-alive related command error The firmware does not like the host configuring the keep-alive after it has been once configured after a join-operation. Instead, it will complain about invalid parameters, which do not break functionality, but do not look nice in the syslog either. This patch prevents the complaints by only configuring the keep-alive once for an association, after the first time join is performed with the correct bssid.
