From 4df378a10e31698df1679f3329301d773a654b61 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 28 Apr 2011 11:29:03 -0700 Subject: Bluetooth: Add store_hint parameter to mgmt_new_key Even for keys that shouldn't be stored some use cases require the knowledge of a new key having been created so that the conclusion of a successful pairing can be made. Therefore, always send the mgmt_new_key event but add a store_hint parameter to it to indicate to user space whether the key should be stored or not.
