In this case, the MAC handles generating and parsing physical frames and the PHY handles how this data is actually moved to/from the wire. The MAC and PHY communicate via a special protocol, known as MII. This MII protocol can handle control over the PHY which allows for selection of such transmission criteria as line speed, duplex mode, etc.Support for the Cicada 8201 PHY, a.k.a Vitesse VSC8201.

Ubuntu wants to use the forcedeth driver for the ethernet port, but (for me) that driver only works if I power down then boot into ubuntu (I dual boot with winxp). If I have been in xp and just reboot into ubuntu, it won't work. So, as a workaround, I have been using the NVIDIA nforce drivers (for the ethernet only, not the sound as it works with the ALSAdriver), and it works fine if you unload both drivers (forcedeth and nvnet), then modprobe nvnet, then reconfigure networking (sudo invoke-rc.d networking restart).forcedeth 23428 0compile and use Nvidia's nvnet network driver rather than forcedethNFORCE-Linux-x86_64-1.0-0306-pkg1.runnvnet.koMCP51 nvnet----tc command set Netem Network Emulation functionalityhttp://linux-net.osdl.org/index.php/Netem # tc qdisc add dev eth0 root netem delay 100msIn g4u Ghost For Unix ghost for unixNow set the IP address by running the command ifconfig <ip address> netmask<subnet mask>.
