Hi Vince,
I may understood the RO pointer in I210 flash.
For example: SMBus 0 slave address Flash Word Offsets: 0x51, Global MNG Offset: 0x06, Offset: 0x03, Bit[7:1]
0x51 address flash value is 0x0080 so 0x0080 is next start address for Global MNG Offset.
Global MNG Offset: 0x06 means 0x0086 address and the value is 0x017E.
Offset: 0x03 means 0x0181 address and the value is 0x0092 so SMBus 0 slave address(Bit[7:1]) is 0x49.
If any misunderstanding, please kindly advise it. Appreciate your support.
