From 21c0cbe760ca6b5d4c6927c3ec1352a843a8c11c Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Fri, 28 Mar 2008 16:33:34 -0700 Subject: [PATCH] mac80211: add association capabilty and timing info into bss_conf This patch adds assocation capability, timestamp (tsf) and beacon interval to bss_conf. This is required for successful assocation of iwlwifi drivers Signed-off-by: Tomas Winkler Signed-off-by: Gregory Greenman Signed-off-by: John W.
