Hello,

We have designed custom board, which is having IMX6DL dual core processor running linux Kernel 4.1.15. we have connected eMMC and Wi-Fi module (88W8997) on SDIO interface

I am stuck with an interesting issue with latest wifi driver as it has changed uap0 MAC address. 

With an slightly old driver wifi uap0 interface was having MAC address: 74:7A:90:C7:36:D5 but after upgrading to latest driver wifi uap0 interface changed it MAC address: 76:7A:90:C7:36:D5

The real problem is that mine is IOT device so I have registered dozen of such device to cloud with unique key as uap0 MAC address (thinking MAC address of wifi STA wont change) so Now I cant upgrade imx6 device with latest wifi driver and release are getting block. Can someone please look in to it?

Hello,

This issue is due to the driver in 4.1.15, however since 5,15 is not present. Please upgrade your kernel.

Regards

@Bio_TICFSL Thank you for the response...
Can we get a little background of which part of driver code it refers to set second bit of first octat? What does it mean to have different MAC address as per different Kernel version?
