Hi Pali,

NXP doesn't have a plan to support mwifiex driver anymore. How should we ha= ndle this kind of retired project in upstream?

Thanks,

Hello Prashanth!

Thank you for reply. Did you have a time to check this issue?

G=E9rald did a great testing which shows that version W16.68.1.p195 and
higher of pcieuart8997_combo_v4.bin firmware does not work.
