From 78b781ca0d35191ebf8d8cad8beec810270f0f2e Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 5 Jan 2016 13:19:32 +0200 Subject: Bluetooth: Add support for Start Limited Discovery command This patch implements the mgmt Start Limited Discovery command. Most of existing Start Discovery code is reused since the only difference is the presence of a 'limited' flag as part of the discovery state.
