NET+OS 6.3 CC7U UNC20 not booting defaut MAC 00:04:F3:00:06:35 OUI

New CC7U ConnectCore 7U (UNC20) modules don't boot with old custom NET+OS 6.3 firmware, or the firmware shows always same default MAC address: 00:04:F3:00:06:35 or other malfunction of firmware due to assumption that MAC starts with 00:04:F3:.. but was changed by Digi to 00:40:9D:.. OUI

Either remove the check for FS-Forth 00:04:F3:.. OUI, or add additional check for Digi 00:40:9D:.. OUI in src/bsp/platforms/unc20/boardParams.c about line 1445. E.g. you might apply the following patch:
