Description

The Realtek RTL88018 is a highly integrated and cost-effective single-chip Fast Ethernet controller. It provides 32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3u 100Base-TX specifications and IEEE 802.3x Full Duplex Flow Control. The RTL88018 also supports the Advanced Configuration Power management Interface (ACPI) and PCI power management for efficient power management. Unlike the RTL8139C, the RTL88018 no longer supports CardBus mode.
