From dfd9774c5ad4abe9d51e52056e441eaf983b9080 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 27 Jan 2014 15:11:34 -0800 Subject: [PATCH] Bluetooth: Fix disconnecting L2CAP channel for credits violation The L2CAP specification requires us to disconnect a channel if the remote device sends us data when it doesn't have any credits to do so. This patch makes sure that we send the appropriate L2CAP Disconnect request in this situation.
