From 7c4cbb6ee0a55885d697a5b07b6c4c8fd10d573a Mon Sep 17 00:00:00 2001 From: Abhijeet Kolekar Date: Fri, 27 Feb 2009 16:21:20 -0800 Subject: [PATCH] iwl3945: synchronize timestamp with uCode In IBSS, TSF maintains local clock counters at each station. Network Synchronization follows a completely distributed scheme where beacon frames are generated. Each station maintain its own TSF timestamp, extracted from beacon timestamps they recieved. Following patch synchronize this beacon timestamp with uCode. Signed-off-by: Abhijeet Kolekar Signed-off-by: Reinette Chatre Signed-off-by: John W.
