From 66138ce8e556a8ddd13baf035fb3a8d0d6dd4bb5 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 10 Jan 2014 02:07:20 -0800 Subject: Bluetooth: Add support for handling P-256 derived link keys Before being able to enable Secure Connections support, the core needs to know on how to handle P-256 derived link keys. The difference between authenticated and unauthenticated P-256 derived link keys is the same as its P-192 counter parts.
