From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tony Cheneau Subject: [PATCH net-next 08/15] 6lowpan: obtain IEEE802.15.4 sequence number from the MAC layer Date: Tue, 23 Oct 2012 00:09:50 -0400 Message-ID: <1350965397-12384-9-git-send-email-tony.cheneau@amnesiak.org> References: <1350965397-12384-1-git-send-email-tony.cheneau@amnesiak.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Cc: netdev-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Alan Ott , linux-zigbee-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org To: "David S.

Without this fix, the sequence number is always set to 0. This makes trafic analysis very hard.
