03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. 
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
        Subsystem: ABIT Computer Corp. Unknown device 240b
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. 
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
        Subsystem: ABIT Computer Corp. Unknown device 240b
