From 98f7dfd86cbbd377e2cbc293529681b914296f68 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Fri, 18 Jul 2008 13:52:59 +0800 Subject: mac80211: pass dtim_period to low level driver This patch adds the dtim_period in ieee80211_bss_conf, this allows the low level driver to know the dtim_period, and to plan power save accordingly.
