From 00e3112c5a90963bb7b56e0648d22fc51ed17d23 Mon Sep 17 00:00:00 2001 From: Mat Martineau Date: Fri, 23 Mar 2012 16:56:56 -0700 Subject: [PATCH] Bluetooth: Add a structure to carry ERTM data in skb control blocks Every field from ERTM control headers is now carried in the control block so it only has to be parsed or generated once, and can be efficiently accessed throughout the ERTM code.
