Hello all, [ Posted on both linux-net and linux-kernel ] Using kernel-2.2.16-3 (Redhat) on P3/650 (UP). I just got a D-Link DFE-570TX Quad Ethernet card. It seems to use DC21143 chipset. Has anyone managed to get this card working in forced full duplex/100 Mb? More of the problems encountered below. Initial tests show that it works OK with tulip in autonegotiation mode. With de4x5 drivers in auto-negotiation mode, there is one irritating problem. If you have configured your interface up, and then plug out the UTP cable, you'll get the following errors ad infinitum: --- eth2: media is unconnected, link down or incompatible connection. eth2: media is 100Mb/s. eth2: media is unconnected, link down or incompatible connection. eth2: media is 100Mb/s. eth2: media is unconnected, link down or incompatible connection. eth2: media is 100Mb/s. --- Repeated at about one second's intervals. Apparently the driver always tries to take up the interface no matter what. I have also tried to take up all interfaces save one to see if it'd homehow fail because _other_ ports are down, but that didn't help any. This won't happen with my other one-port DE500-BA using the same drivers. This isn't a show-stopper though. Both de4x5 (either from 2.2.16-3 or the one from 2.2.17pre12) and tulip fail to work properly in forced full duplex, 100Mb environment. With de4x5, you'll just get an error: eth2: media is unconnected, link down or incompatible connection full duplex. Even ARP resolution won't work. New 2.2.17pre12 worked like a charm on my other, one-port DE500-BA though. With tulip, you get no warnings but it just won't work. I tried both options=5,5,5,5 and options=14,14,14,14 arguments. Tulip drivers on Donald Becker's site seemed significantly different, but I wasn't able to test with them; all I got was: --- tulip.o: unresolved symbol pci_drv_unregister tulip.o: unresolved symbol pci_drv_register --- I'm no driver/kernel guy, but perhaps some might have ideas what might be going on here. I can naturally test anything you can throw at my direction ;) (Please Cc: any relevant follow-ups to me) Regards, -- Pekka Savola "Tell me of difficulties surmounted, Pekka.Savola@netcore.fi not those you stumble over and fall" - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
