From c006aa0c5627e27e6cc422636a4744c43cbd5dc9 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Thu, 30 Jun 2011 19:20:55 -0300 Subject: [PATCH] Bluetooth: Add lmp_host_le_capable() macro Since we have the extended LMP features properly implemented, we should check the LMP_HOST_LE bit to know if the host supports LE.
