2025-05-07wifi: iwlwifi: handle v3 ratesJohannes Berg
For UHR, a version 3 of the rate API is being added, which increases the number of bits used for MCSes by shifting the NSS bit up. Handle that.

2023-09-11wifi: iwlwifi: mvm: move RU alloc B2 placementJohannes Berg
The firmware was trying to report the B2 RU allocation in the place previously used here as well, but there's a HW block that clears the lower 8 bits in this metadata word even in sniffer mode. Thus, firmware moved B2 to another place, follow that. There's no need to detect the version since moving it to the other place if firmware didn't just means that we'll continue to report the (erroneous) zero value, and it's not really something we can detect from the firmware now. While debugging this we realized that the comments about placement in the metadata dwords are wrong, update them.

2019-09-06iwlwifi: mvm: handle BAR_FRAME_RELEASE (0xc2) notificationJohannes Berg
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

The firmware changed the PHY data API, so follow suit. Some data is now available even for HT/VHT frames, so the info type in the metadata was changed. This change isn't backwards compatible, but 1) the firmware with the old API was never released; 2) the only overlap in the info type field is from the old type of TB to the new of HT, so this basically just means that with older FW and newer driver the data will be considered missing. While at it, remove the extra code to set the LTF syms corresponding to the streams and use the data from the device instead - we don't really need this in any case other than when we have it from the device.

In some cases we may get from FW errored frames with UNKNOWN security type.

The next frames in the aggregation "inherit" the bad metadata of the first packet. Make sure to drop such frames since RADA and other offloads will not operate correctly which may have unexpected results.
