From 08601469a5aac8b3453d8aca0b8f9bd8dfdae12c Mon Sep 17 00:00:00 2001 From: Yuri Kululin Date: Fri, 23 Jul 2010 13:57:12 +0400 Subject: [PATCH] Bluetooth: Fix RFCOMM RPN negotiation According to the ETSI 3GPP TS 07.10 the default bit rate value for RFCOMM is 9600 bit/s. Return this bit rate in case of RPN request and accept other sane bit rates proposed by the sender in RPM command. Signed-off-by: Yuri Kululin Signed-off-by: Marcel Holtmann Signed-off-by: Gustavo F.
