Subject: GigE on PowerMac G5

Message-ID: <jebqwmfeh9.fsf@sykes.suse.de> (raw)
[Sorry for duplicate posting, I've used the wrong list address.]
I suppose the NIC in the PowerMac G5 can do GigE, yet when plugged into a
GB switch it is only willing to talk 100MB with it. Any idea why? Kernel
is 2.6.16-rc5-git2.
