If anyone has any objections, please let me know. ------------------ From: P Praneesh [ Upstream commit a6621bf6397ae6981b5041ba0a127e7dbeade746 ] Currently, error bitmap and decap format information are fetched from the MSDU Rx TLV data. This logic is inherited from ath11k. However, for ath12k 802.11be hardware, the Rx TLV will not be present in the MSDU data. Instead, this information is reported separately under the MSDU END TLV tag. Therefore, remove the existing fetch code, handle the MSDU END TLV tag and fetch the above information to store it in the mon_mpdu data structure for use in the merge MSDU procedure.
