From 9c9613f0ee07b8da049914d92fc735a0e954d777 Mon Sep 17 00:00:00 2001 From: Luca Coelho Date: Sat, 18 Apr 2020 11:08:55 +0300 Subject: [PATCH] iwlwifi: pcie: add new structure for Qu devices with medium latency Some Qu devices require an intermediate amount of time to wake up and for LTR notifications, so add a new structure with the correct values for them and change the corresponding devices to use it.
