From cdb00563fe2c25a782d2fc57ad1778280fbf9edb Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Sun, 16 Mar 2014 21:55:43 +0200 Subject: iwlwifi: mvm: BT Coex - add debugfs hook to set BT Tx priority In order to debug the firmware, we need to be able to set the BT priority of WiFi packets. This priority is set based on the type of the packet (control frames, EAPOL etc...). For debugging purposes, allow to override this priority by a debugfs controlled value. Enable this feature that needs this priority to be able to test it.
