From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Andrei Emeltchenko To: linux-bluetooth@vger.kernel.org Subject: [PATCHv2] Bluetooth: Save remote L2CAP fixed channel mask Date: Wed, 29 Feb 2012 10:41:41 +0200 Message-Id: <1330504901-28428-1-git-send-email-Andrei.Emeltchenko.news@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Andrei Emeltchenko Fixed channel mask needs to be stored to decide whether to use A2MP for example. So far save only one relevant byte which keeps all information we need.
