From 95fbac8a8e459262c580ee4172e4713cdc60929b Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 19 Feb 2014 15:18:31 +0200 Subject: [PATCH] Bluetooth: Add support for sending New IRK event This patch adds the necessary helper function to send the New IRK mgmt event and makes sure that the function is called at when SMP key distribution has completed. The event is sent before the New LTK event so user space knows which remote device to associate with the keys.
