From ec18e7d4d20dc6be85aaf02dfa3cebbb136a7c26 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 2 Nov 2022 16:59:48 +0200 Subject: [PATCH] wifi: iwlwifi: mvm: use old checksum for Bz A-step For Bz A-step hardware, the checksum offload is broken and we need to use the old way, which is still there. Do that, which requires taking the checksum capability bits out of the IWL_DEVICE_BZ macro and listing them individually.
