From 301cb2d85eb89140eaff8c22066a4bfd774960a3 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 18 Feb 2014 10:19:34 +0200 Subject: [PATCH] Bluetooth: Add hci_bdaddr_is_rpa convenience function When implementing support for Resolvable Private Addresses (RPAs) we'll need to in several places be able to identify such addresses. This patch adds a simple convenience function to do the identification of the address type.
