I've just installed F13/x64 on a brand new Athlon II x2 240 based system.

Motherboard: GigaByte GA-880GM-UD2H (not GA-EP45-DS5 as lspci reports below).
Kernel: 2.6.33.6-147.2.4.fc13.x86_64

During the install, from the F13/x64 Live-USB, I was unable to get a DHCP lease using this card. I has to use a USB network card in order to even complete the install (for some reason anaconda would crash if it couldn't get network access)

After install, this card still wouldn't work, so I performed a full "yum update" using the USB card and rebooted into the current kernel.

I now have network access using the onboard RTL card, but I observe the following oddities:

My router, a Juniper Netscreen 5GT (with a 4-port 100/Full switch) is reporting the link as:

  ns5gt-adsl-wlan-> get int trust port phy  
  Port 1:  link is up, 100 Mbps, auto negotiated to full duplex

ethtool, however, reports the link as up at 10Mb/Half Duplex.

# ethtool eth0
Settings for eth0:
	Supported ports: [ TP MII ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Half 1000baseT/Full 
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full 
	                        100baseT/Half 
	Advertised pause frame use: No
	Advertised auto-negotiation: Yes
	Speed: 10Mb/s
	Duplex: Half
	Port: MII
	PHYAD: 0
	Transceiver: internal
	Auto-negotiation: on
	Supports Wake-on: pumbg
	Wake-on: g
	Current message level: 0x00000033 (51)
	Link detected: yes

Regardless of what I try and force on the card via ethtool (I've tried forcing autoneg off, speed 100, duplex full etc) it won't display the same speed/duplex that the router says. Nor will it renegotiate.

# ethtool -r eth0
Cannot restart autonegotiation: Operation not supported

I know which device I trust to tell me what I'm actually negotiated at, and it's not at the Linux end of the cable :o)

Incidentally, I find it a little odd that neither mii-tool or ethtool want to advertise 100/Full.
