Routing from incomming Ethernet Frames to sockets

Ich have a W5500 Chip.
Configured
Socket 0 as MACRAW with enable MAC Filtering
Socket 1 as UDP Port
Socket 2 as TCP/IP

Socket 0 should not receive Ethertype 0x0800
Whats the routing mechanism from the incomming Ethernet Frame to the sockets???
Is there any documentation?

This is an excerpt from the datasheet.
Please note.
