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.
