Introduction

Unless specifically noted, 82573 refers to the Intel? 82573E, 82573V and 82573L GbE controllers.

82573 GbE controllers are single, compact components with integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) functions. These devices use PCIe* architecture (Revision 1.0a). For desktop, workstation, and value server network designs with critical space constraints, the 82573 enables a GbE implementation in a very small area.

The 82573 provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab, respectively). In addition to managing MAC and PHY Ethernet layer functions, the 82573 manages PCIe* packet traffic across its transaction, link, and physical and logical layers.
