From fe69b7d1243a42fedee944e873e80456a743c964 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 4 Jul 2019 17:24:47 +0200 Subject: iwlwifi: mvm: handle BAR_FRAME_RELEASE (0xc2) notification In prior hardware generations (e.g. 9000 series), we received the BAR frame with fake NSSN information to handle releasing frames from the reorder buffer for the default queue, the other queues were getting the FRAME_RELEASE notification in this case. With multi-TID block-ack, the firmware no longer sends us the BAR frame because the fake RX is quite big (just the metadata is around 48 bytes or so). Instead, it now sends us one (or multiple) special release notifications (0xc2). The hardware consumes these as well, but only generates the FRAME_RELEASE (0xc3) for queues other than the default queue. We thus need to handle them in the same way we handle the normal FRAME_RELEASE.
