From 41d2f291d78fb90ec26122c1c67d0c151965b378 Mon Sep 17 00:00:00 2001 From: "John W. Linville" <linville@tuxdriver.com> Date: Fri, 20 Feb 2009 19:03:31 -0500 Subject: [PATCH] iwlagn: default to MAX_UCODE_BEACON_INTERVAL in iwl_adjust_beacon_interval Default to MAX_UCODE_BEACON_INTERVAL if the output of iwl_adjust_beacon_interval would otherwise be zero. This prevents a division by zero on my iwl5300-equipped Lenovo T400 with kernels that include "mac80211: use cfg80211s BSS infrastructure". This patch is a bit of a hack -- I'm not sure why iwl_setup_rxon_timing is giving iwl_adjust_beacon_interval a zero input (which is the only way it would output zero). I would be happy to have a better fix. But for now, this makes my box boot... Signed-off-by: John W.
