From 48264f06943e2db2c971b752949606f070d9d292 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 9 Nov 2011 13:58:58 +0200 Subject: [PATCH] Bluetooth: Add public/random LE address information to mgmt messages It's necessary to know the distinction between public and random LE addresses so the mgmt interface also needs to distinguish between them.
