want set mac number.

2 issues:
1. see there lot of free space in otp memory. how can program otp memory? possible?
2. how set mac based on information stored in otp? part of code now?

where see there lot of space ?
easy answer no - long answer not
don't change mac via otp
can change via
ip link set dev interface xx.xx.xx.xx.xx
