From: Luca Coelho luciano.coelho@intel.com Date: Mon, 8 Jul 2019 18:55:34 +0300 Subject: [PATCH] iwlwifi: pcie: add support for qu c-step devices
Add support for C-step devices. Currently we don't have a nice way of matching the step and choosing the proper configuration, so we need to switch the config structs one by one.
