1.2.1.2.4 Ethernet interface
This interface is the connection to a processor module with onboard Ethernet e.g.
PM56xx-2ETH.
TB56xx-2ETH for processor modules PM56xx-2ETH provide 2 independent
Ethernet interfaces.
The two Ethernet interfaces can be configured as independent interfaces or with
switch functionality.
In case of two independent interfaces they must be configured to different
subnets.
For structured Ethernet cabling only use cables according to TIA/EIA-568-A,
ISO/IEC 11801 or EN 50173.
