FYI: There is a new NXP driver for these ex-Marvell wifi chips: https://source.codeaurora.org/external/nxpwifi/mwifiex/tree/mxm_wifiex/wlan_src/mlinux?h=caf/master And NXP has there also some modified mwifiex driver: https://source.codeaurora.org/external/nxpwifi/mwifiex/tree/mwifiex_8997/mlinux?h=caf/master&id=070397228c46e0a6afce4f627b032d3818cc1356 Maybe somebody could be interested in looking into those NXP driver modifications... Maybe NXP fixed some issues here. Also look at another new bug report related to mwifiex firmware: https://lore.kernel.org/linux-wireless/edeb34bc-7c85-7f1d-79e4-e3e21df86334@xxxxxxx/
