From a40c406cbdd28dcca3483065bc2ba794cf5aaab7 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 8 Dec 2010 00:21:07 +0200 Subject: Bluetooth: Make hci_send_to_sock usable for management control sockets In order to send data to management control sockets the function should: - skip checks intended for raw HCI data and stack internal events - make sure RAW HCI data or stack internal events don't go to management control sockets In order to accomplish this the patch adds a new member to the bluetooth skb private data to flag skb's that are destined for management control sockets.
