From 8f2535b92d685c68db4bc699dd78462a646f6ef9 Mon Sep 17 00:00:00 2001 From: Chun-Yeow Yeoh Date: Mon, 14 Oct 2013 19:08:27 -0700 Subject: mac80211: process the CSA frame for mesh accordingly Process the CSA frame according to the procedures define in IEEE Std 802.11-2012 section 10.9.8.4.3 as follow: * The mesh channel switch parameters element (MCSP) must be availabe. * If the MCSP's TTL is 1, drop the frame but still process the CSA. * If the MCSP's precedence value is less than or equal to the current precedence value, drop the frame and do not process the CSA. * The CSA frame is forwarded after TTL is decremented by 1 and the initiator field is set to 0. Transmit restrict field and others are maintained as is. * No beacon or probe response frame are handled here. Also, introduce the debug message used for mesh CSA purpose.
