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 still needed for wilink8 as well. This broke user space backward compatibility when upgrading from older kernels, as the alternate mac address would not be read from the nvs that is already present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin) causing mac address change of the wlan interface. This patch fix this and update the structure field with the same default nvs file 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.
