The following commits:
c815fde wlcore: spi: Populate config firmware data
d776fc8 wlcore: sdio: Populate config firmware data
Populated the nvs entry for wilink6 and wilink7 only while it is=20
still needed for wilink8 as well.=20
This broke user space backward compatibility when upgrading from older=20
kernels, as the alternate mac address would not be read from the nvs that i=
s=20
already present in the file system (lib/firmware/ti-connectivity/wl1271-nvs=
.bin)=20
causing mac address change of the wlan interface.
This patch fix this and update the structure field with the same default nv=
s file=20
name that has been used before.
In addition, some distros hold a default wl1271-nvs.bin in the file
system with a bogus mac address (deadbeef...) that for a wl18xx device
also overrides the mac address that is stored inside the device.
Warn users about this bogus mac address.
