From a7481beb039a29f4e384e2f70e40747b19f19703 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Thu, 7 Jul 2011 18:59:35 -0300 Subject: [PATCH] Bluetooth: Add new structures for supporting SM key distribution We need these changes because SMP keys may have more information associated with them, for example, in the LTK case, it has an encrypted diversifier (ediv) and a random number (rand).
