The following error messages were encountered while parsing fragmented RX packets for WCN6750/WCN6855: ath11k 17a10040.wifi: invalid return buffer manager 4 This issue arose due to a hardcoded check for HAL_RX_BUF_RBM_SW3_BM introduced in 'commit 71c748b5e01e ("ath11k: Fix unexpected return buffer manager error for QCA6390")' For WCN6750 and WCN6855, the return buffer manager ID should be HAL_RX_BUF_RBM_SW1_BM. The incorrect conditional check caused fragmented packets to be dropped, resulting in the above error log. Fix this by adding a check for HAL_RX_BUF_RBM_SW1_BM.
