I think this came up a while back, and no one had any clues, but this device doesn't seem to be fully supported in 4.7-REL. The adapter itself is, but I always get an error message about there being no supported PHY's - which is interesting, because there are actually two MII phy's in the ASIC. Here is the kernel info: pcn0: <AMD PCnet/Home HomePNA> port 0x1c00-0x1c1f mem 0x41200000-0x4120001f irq 9 at device 5.0 on pci0 pcn0: Ethernet address: 00:01:fa:ff:ac:57 pcn0: MII without any PHY! device_probe_and_attach: pcn0 attach returned 6 I have configured my kernel thusly: # PCI Ethernet NICs that use the common MII bus controller code. # NOTE: Be sure to keep the 'device miibus' line in order to use these NICs! device miibus0 # MII bus support device miibus device xl # 3Com 3c905c support device pcn # AMD PCnet32/PCI support # Pseudo devices - the number indicates how many units to allocate. pseudo-device loop # Network loopback pseudo-device ether # Ethernet support pseudo-device tun # Packet tunnel. pseudo-device pty # Pseudo-ttys (telnet etc) pseudo-device md # Memory "disks" #pseudo-device gif # IPv6 and IPv4 tunneling #pseudo-device faith 1 # IPv6-to-IPv4 relaying (translation) # The `bpf' pseudo-device enables the Berkeley Packet Filter. # Be aware of the administrative consequences of enabling this! pseudo-device bpf #Berkeley packet filter # USB support device uhci # UHCI PCI->USB interface device ohci # OHCI PCI->USB interface device usb # USB Bus (required) device ugen # Generic device uhid # "Human Interface Devices" device ukbd # Keyboard device ulpt # Printer device umass # Disks/Mass storage device ums # Mouse # USB Ethernet, requires mii device aue # ADMtek USB ethernet device cue # CATC USB ethernet device kue # Kawasaki LSI USB ethernet (note - I only included the network and USB sections for brevity) the xl driver was included for development builds - as my development PC has a 3Com nic in it (just makes things easier) Does anyone know if this is on the bug-board, or fixed in the next release? I ask only because I can't replace it - it is built into the Compaq IA-1's with ethernet. Presently, I am working around the issue with a USB NIC, but performance is far from optimal.
