From: Christian Lamparter Date: Wed, 8 Oct 2008 18:52:22 +0000 (+0200) Subject: p54: honour bss_info_changed's short slot time settings X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=40333e4fb476014cdd939d27e20eb54573172b32;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git p54: honour bss_info_changed's short slot time settings This patch was made on behalf of Johannes request. "mac80211 and IEEE80211_CONF_SHORT_SLOT_TIME" Of course, bss_info_changed provides some more useful data. e.g.: basic_rates, dtim_period, beacon_int and maybe even more. Everything can be hooked up if it's necessary. Signed-off-by: Christian Lamparter Signed-off-by: John W.
