>Description:
When I boot FreeBSD 9.1 with the Realtek 8111G controller on an Asus H87M-E motherboard, it says "Unknown H/W revision".

dmesg snapshot:
re0: <RealTek 8168/8111 B/C/CP/D/DP/E/F PCIe Gigabit Ethernet> port 0xd000-0xd0ff mem 0xf3104000-0xf3104fff,0xf3100000-0xf3103fff irq 18 at device 0.0 on pci3
re0: Using 1 MSI-X message
re0: turning off MSI enable bit.
re0: Chip rev. 0x4c000000
re0: MAC rev. 0x00000000
re0: Unknown H/W revision: 0x4c000000

>How-To-Repeat:
1. Load FreeBSD on a computer with a Realtek 8111G controller
2. See the dmesg output that says that the HW revision is unknown
>Fix:
I did set up patches to support the ethernet controller. The patches are:
