Does W8997 support second AP interface

[changbaoma]

Hello, NXP experts

UBLOX says NXP W8987 wifi modules support second AP interface in document https://manuals.plus/m/dd1dc6828d4f28d093892c32d507a4091e8dde3d8f29a0766ef5a3084276212e.pdf ，see below：

I add the parameter max_uap_bss=2 when loading the my w8997 sdio driver, but don't see uap1 appear.

My w8997 use the drivers/net/wireless/nxp/mxm_wifiex of NXP linux kernel 5.4( Linux 5.4.70_2.3.0​ + Linux 5.4.70_2.3.1 Patch). 

And i have tried the firmware sdsd8997_combo_v4.bin from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mrvl and sdsd8997_combo_v4.bin form Marvell's SD-WLAN-SD-BT-8997-U16-MMC-W16.68.10.p137-16.26.10.p137-C4X16687_V4-MGPL\FwImage, uap1 never showed up.

Hi @changbaoma 

>>Can i change MAX_UAP_BSS to above 2, eg 4/8 ?

No, you can't.

1 MAC can support max 2 uaps. 

>>About SDIO driver for 8997

Yes, we have. But NDA is required.

you can submit a new case for NDA on our website, our TSR team will help you sign it.

After NDA is done, apply for the driver source code by creating a new case on website, don't forget to provide your NDA number.

Hi @changbaoma ,

Enter wlan_src directory, and change MAX_UAP_BSS to 2.

-------------

./mlinux/moal_main.h:936:#define MAX_UAP_BSS 1

--------------

Then add max_uap_bss=2 to parameter list when loading driver.

Try it, plese!

Thank you very much, @weidong_sun 

Can i change MAX_UAP_BSS to above 2, eg 4/8 ?

As you know the firmware in IMX8M plus EVK board is pcieuart8997_combo_v4.bin, which is not for SDIO w8997. And how can't i get the proper firmware for my SDIO w8997, which adapted to the drivers/net/wireless/nxp/mxm_wifiex of NXP linux kernel 5.4?
