Description

Ethernet routines enable communication over an Ethernet-based IP network.

Ethernet is a family of networking technologies for local area (LAN) and wider networks. It was introduced and standardized in the 1980's as IEEE 802.3, and has since been updated regularly to support higher bit rates and longer link distances. Most embedded microcontrollers with Ethernet support bit rates of up to 100 Mbit/s which is also fully supported by the Network Component.

This documentation is separated as follows:

• User API explains the Ethernet API of the Network Component.
• User Callbacks describes the user callback functions that can be used to notify the application about events on the Ethernet interface.
• IP Address Assignment describes the various methods that are used to assign an IP address to the embedded system.
• Configuration explains the configuration options of the Ethernet interface.

Checksum Offloading

The Network Component also supports the Checksum offloading. To send the packet, the network library will not calculate the checksum itself, but would simply hand over an empty checksum field to the driver. For the receiving packet, the network library won't validate the checksum fields in the packet. To use the checksum offloading, it must be supported by the ethernet driver.
