Hi all,

where do I find information about the current link state of the ethernet PHY (e.g. 100mbit/s full duplex) ?
Something like /proc/sys/net/* ?

Thanks
Bernhard

I don't have an answer but a related question:
Is there any "standard ioctl" to force an interface to a certain link state, eg. auto, 10Mbs, 100Mbps, half/full duplex etc.?

If not, can we create a standard ioctl mechanism for it?

     Learning French is trivial: the word for horse is cheval, and
               everything else follows in the same way.

/sbin/mii-tool should do this on most network cards.
