The RTL8211F series can monitor the network for a link change event, 
a Wake-Up Frame, or a Magic  Packet, and notify the system via the INTB/PMEB (Power Management Event; ‘B’ means low active) pin  
when such a packet or event occurs. The system can then be restored to a normal state to process incoming  jobs. 
The INTB/PMEB pin needs to be connected with a 4.7k ohm resistor and pulled up to 3.3V. 
When  the Wake-Up Frame or a Magic Packet is sent to the PHY, the INTB/PMEB pin will be set low to notify  the system to wake up. 

For example,
 1.Set MAC Address Page 0x0d8c, Reg16~Reg18 
 2.Set Max packet length Page 0xd8a, Reg17 = 0x9fff
 3.WOL event select and enable Page 0x0d8a Reg16 =  0x1000 //enable Magic Packet Event

Kind regards，
