近幾年的 Intel 主機板南橋晶片 , 所謂的內建 MAC , 該不會只能對應自家晶片 .
又或者是 , 一顆 Intel PHY 價格能抵得上一顆他牌 LOM , 所以沒人要用 .

看多數主機板所搭載的 Marvell / Realtek , 其實都是走 PCIe 介面的 LOM , 並
不是 PHY 晶片說 ...

Realtek PHY :
RTL8211B Single-Port 10/100/1000M Gigabit Ethernet PHYceiver
RTL8211C/RTL8211CL Integrated 10/100/1000 Gigabit Ethernet Transceiver
RTL8211BG-GR Integrated 10/100/1000 Gigabit Ethernet Transceiver
幾乎沒見過 .

Realtek LOM :
RTL8111B Single-Chip Gigabit LOM Ethernet Controller for PCI Express
RTL8111C Integrated Gigabit Ethernet Controller for PCI Express Applications
大家相當熟悉 .

Marvell LOM :
Yukon 88E805X PCI Express Gigabit Ethernet Controller Family
Yukon 88E803X PCI Express Fast Ethernet Controller Family
88E805X 這顆華碩用過不少 .
