Link Auto Negotiation

To enable Link Auto Negotiation, use the (pseudo) module stm32_eth_auto by amending your applications Makefile as follows:

# Add the following line to your Makefile
USEMODULE += stm32_eth_auto
 
# Note: Any addition of modules to USEMODULE must be done prior to the
# following line:
include $(RIOTBASE)/Makefile.include

In general, it is highly recommended to use auto-negotiation, as this can avoid various communication issues on the PHY layer due to configuration mismatch of the link partners. Note that this feature depends on the link state events feature.

Link State Events

To enable Link Events, use the (pseudo) module stm32_eth_link_up (as described above).
