Subject: Re: [Bugme-new] [Bug 11754] New: tlan network driver does not work

I had a look on the ethernet pci-card LAN-LED and the DSL-Modem LAN-LED. 
It seems to be that the packets were sent out are going over the
wire, the ethernet pci-card LAN-LED and the DSL-Modem LAN-LED blinks
three times. It seems so that the replayed packets are dropped.
