Return-Path: From: Mat Martineau To: linux-bluetooth@vger.kernel.org Cc: padovan@profusion.mobi, pkrystad@codeaurora.org, marcel@holtmann.org, Mat Martineau Subject: [PATCH 2/4] Bluetooth: Add a structure to carry ERTM data in skb control blocks Date: Fri, 23 Mar 2012 16:56:56 -0700 Message-Id: <1332547018-19468-3-git-send-email-mathewm@codeaurora.org> In-Reply-To: <1332547018-19468-1-git-send-email-mathewm@codeaurora.org> References: <1332547018-19468-1-git-send-email-mathewm@codeaurora.org> List-ID: 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.
