I guess ukphy(4) is not right phy driver for the hardware as it could result in non-working driver. Would you show me the ukphy(4) output of verbosed boot message?(In verbosed boot mode, ukphy(4) may have printed OUI/model number of the PHY hardware.) > ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT-FDX, auto > nfe0: Ethernet address: 00:1d:60:6d:73:ec > nfe0: [FILTER] > nfe0: [FILTER] > nfe0: [FILTER] > nfe0: [FILTER] > nfe0: [FILTER] > nfe0: [FILTER] > nfe0: [FILTER] > nfe0: [FILTER] > pcib2: <ACPI PCI-PCI bridge> at device 11.0 on pci0 > > and ifconfig -a gives: > > nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > options=48<VLAN_MTU,POLLING> > ether 00:1d:60:6d:73:ec > inet 192.168.1.11 netmask 0xffffff00 broadcast 192.168.1.255 > media: Ethernet 100baseTX <full-duplex> > status: active > -- Regards, Pyun YongHyeon
