[SD8997] iwpriv private ioctl not supported

[john2207]

Hi Support,

In our custom board, our i.MX6UL SOC connected with AW-CM276 (SD8997) wifi module with SDIO interface. We are using NXP latest wifi driver/firmware (version : 16.92.10.p218-MM5X16247.p5-GPL-(FP92)) and trying to use the private ioctl's using iwpriv command.

But the private IOCTL's are not supported and getting error as "Interface doesn't accept private ioctl...". Please refer below log and help us on this issue. We also checked our kernel (5.10.9- gatesgarth) config file and confirmed that CONFIG_WIRELESS_EXT and CONFIG_WEXT_PRIV enabled.

Hello John,

Yes, the iwpriv command of 88W8997 does have this problem.

You can use the mlanutl command to achieve your purpose.

or iw tool can also be used.

Have a good day!
