This is bad.  Your device is broken or powered down.
You can get some indication with 'lspci'.

Try '-m' to see if the transceiver is responding.

Uhmmm, you are advertising only 100baseTx.  Perhaps that's not what you
intended.

Is this setting what you intended?

Try hard-power-off (unplug), and see what the 'mii-diag' reports without
forcing the speed.
