There are quite a few models there, and you haven't said which one you

There are 2 important components for an Ethernet interface, a NIC and a
PHY.  The NIC (Network Interface Controller) or MAC (Media Access
Controller) does all the processing of data packets, and is primarily
what the driver talks to.  The PHY (Physical interface) connects the NIC
to the coax, twisted pair cable, fibre, wireless, etc...  For a coax or
twisted pair Ethernet the PHY (in essence) allows data to be received
and transmitted but isolates the PC when the power is off.

The Realtek 8201BL is a PHY.  To know which driver to use you need to
determine what NIC or MAC is in your system.
