From 472e7c25fcc9c39e923a6cbe13d98eb0e4c8dcf1 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).
