If your network driver supports the ETH_DRV_GET_IF_STATS option of the control function, then you can poll the control function. See cyg/io/eth/eth_drv_stats.h for the struct ether_drv_stats.operational.

See http://ecos.sourceware.org/docs-latest/ref/io-eth-drv-api-funcs.html.

Hi,

I try to know what is the Ethernet link status from the application level.
I just would like to write a function like this :     int
eth_link_state ("eth0");      which return 1 if the Ethernet is up.
I want to respect the different ecos layer to do this but I didn't
find any answer in the ecos-discuss history.
Do someone have an idea how to do this properly ?

Thank you for your response.

Emmanuel Coullien
