3. The code is tested with IW416. There is no guarantee for other chips.

I just did a quick scan to see if anything jumped out at me

...

diff --git a/drivers/net/wireless/marvell/mwifiex/fw.h b/drivers/net/wireless/marvell/mwifiex/fw.h

+#define MWIFIEX_AUTHTYPE_SAE 6
+
+struct mwifiex_ie_types_sae_pwe_mode {
+       struct mwifiex_ie_types_header header;
+       u8 pwe[1];

this jumped out, it is not allowed (unless this really is a 1-element array)

see <https://www.kernel.org/doc/html/next/process/deprecated.html#zero-length-and-one-element-arrays>

should just be u8 pwe[];

make sure any code that uses sizeof(struct mwifiex_ie_types_sae_pwe_mode) accounts for the u8 being removed from the struct
