Thanks for pointing out ethtool.  I had earlier seen mii-tool but could
not remember what it was.

The -s you show above allows setting the parameters but does not display
anything about current settings.. 

After some playing with ethtool I found out that the display from
"ethtool ethX" is likely what Anne needs.  Example from mine below.

[root@eagle ~]# ethtool eth0
Settings for eth0:
        Supported ports: [ MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Advertised auto-negotiation: Yes
        Speed: 100Mb/s
        Duplex: Half
        Port: MII
        PHYAD: 1
        Transceiver: external
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: d
        Link detected: yes

Again, Thanks
Jeff
