Wake-up Events
There are two types of wake-up events: “Interesting” Packets and Link Status Change. These two
events are detailed below.
Note:
The wake-up event is supported only if the PME Enable bit in the Power Management Control/
Status (PMCSR) register is set. (The PMCSR is described in
Section 8.1.21, “Power Management
Control/Status Register (PMCSR)” on page 64
.)
4.3.2.1
“Interesting” Packet Event
In the power-down state, the 82559 is capable of recognizing “interesting” packets. The 82559
supports pre-defined and programmable packets that can be defined as any of the following:
ARP Packets (with Multiple IP addresses)
Direct Packets (with or without type qualification)
Magic Packet*
Neighbor Discovery Multicast Address Packet (‘ARP’ in IPv6 environment)
NetBIOS over TCP/IP (NBT) Query Packet (under IPv4)
Internetwork Package Exchange* (IPX) Diagnostic Packet
TCO Packet
This allows the 82559 to handle various packet types. In general, the 82559 supports
programmable filtering of any packet in the first 128 bytes.
