Network interfaces at 100 Full duplex

[Gustavo Mendes de Carvalho <gmcarvalho@gmail.com>]

Hello there,

I´m using a Debian Sarge version for Sparc, running in a E420, and when 
I run ethtool command, I get

server:~# ethtool eth0
Settings for eth0:
       Supported ports: [ TP MII ]
       Supported link modes:   10baseT/Half 10baseT/Full
                               100baseT/Half 100baseT/Full
       Supports auto-negotiation: Yes
       Advertised link modes:  Not reported
       Advertised auto-negotiation: No
       Speed: 100Mb/s
       Duplex: Half
       Port: Twisted Pair
       PHYAD: 0
       Transceiver: internal
       Auto-negotiation: on

What can I do to get a Full duplex setting ?

This server has a quad ethernet card, and I have no cable connected 
there, and because of that I´m receiving this messages

eth1: Link down, cable problem?
eth2: Link down, cable problem?
eth3: Link down, cable problem?
eth4: Link down, cable problem?
eth1: Auto-Negotiation unsuccessful, trying force link mode
eth2: Auto-Negotiation unsuccessful, trying force link mode
eth3: Auto-Negotiation unsuccessful, trying force link mode
eth4: Auto-Negotiation unsuccessful, trying force link mode

What do I have to do to stop to generate this messages ?

Thanks for now
