From 86742e1eca319069490f6f20c2892baafc2a6922 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 7 Nov 2011 23:13:38 +0200 Subject: [PATCH] Bluetooth: Update link key mgmt APIs to match latest spec. BR/EDR link keys have their own commands and events (separate from SMP) and the remove_keys command (previously remove_key) removes keys of any kind for the specified remote address.
