From e2fd318e3a9208245ee1041f6d413c8593fba29d Mon Sep 17 00:00:00 2001 From: Ilia Kolomisnky Date: Sun, 10 Jul 2011 08:47:44 +0300 Subject: Bluetooth: Fixes l2cap "command reject" reply according to spec There can 3 reasons for the "command reject" reply produced by the stack. Each such reply should be accompanied by the relevand data ( as defined in spec. ). Currently there is one instance of "command reject" reply with reason "invalid cid" wich is fixed. Also, added clean-up definitions related to the "command reject" replies. Signed-off-by: Ilia Kolomisnky Signed-off-by: Gustavo F.
