realtek interface not working

[Sreenath Battalahalli]

Hi Marius,

Thanks for the patch. I manually made changes to the two files, and after building the kernel and installing it,
I can see the re0 interface. I am now sending this email using the new laptop.

However, I am a bit confused by the dmesg output. I see two sets of lines pertaining to the re0 device.

$dmesg | grep -i re0

re0: <RealTek 8168/8111 B/C/CP/D/DP/E/F/G PCIe Gigabit Ethernet> port 0x3000-0x30ff mem 0xb0604000-0xb0604fff,0xb0600000-0xb0603fff irq 18 at device 0.0 on pci2
re0: Using 1 MSI-X message
re0: turning off MSI enable bit.
re0: ASPM disabled
re0: Chip rev. 0x54000000
re0: MAC rev. 0x00100000
re0: Unknown H/W revision: 0x54000000
device_attach: re0 attach returned 6
re0: <RealTek 8168/8111 B/C/CP/D/DP/E/F/G PCIe Gigabit Ethernet> port 0x3000-0x30ff mem 0xb0604000-0xb0604fff,0xb0600000-0xb0603fff irq 18 at device 0.0 on pci2
re0: Using 1 MSI-X message
re0: ASPM disabled
re0: Chip rev. 0x54000000
re0: MAC rev. 0x00100000
miibus0: <MII bus> on re0
re0: Using defaults for TSO: 65518/35/2048
re0: Ethernet address: 2c:60:0c:92:0f:c2

seems the driver attempted to initialize the device twice?

Anyway, it is working now.

thanks,
Sreenath
