IOEthernetController.h

Overview

The IOEthernetController class provides a base class for you to use when creating Ethernet controller drivers. If you want to create an Ethernet controller driver, subclass this class and override the hardware-specific methods.

---

Classes

IOEthernetController

Abstract superclass for Ethernet controllers.

---

Constants

---

gIOEthernetWakeOnLANFilterGroup

---

extern const OSSymbol * gIOEthernetWakeOnLANFilterGroup;  

Discussion

gIOEthernetWakeOnLANFilterGroup is an OSSymbol object that contains the name of the Ethernet wake-on-LAN filter group defined by kIOEthernetWakeOnLANFilterGroup.

Enumerations

---

WakeOnLANFilters

---

All filters in the wake-on-LAN filter group.

enum { 
    kIOEthernetWakeOnMagicPacket = 0x00000001, 
    kIOEthernetWakeOnPacketAddressMatch = 0x00000002 
};  

Constants

kIOEthernetWakeOnMagicPacket

Reception of a Magic Packet.

kIOEthernetWakeOnPacketAddressMatch

Reception of a packet which passes through any of the address filtering mechanisms based on its destination Ethernet address. This may include unicast, broadcast, or multicast addresses depending on the current state and setting of the corresponding packet filters.

Discussion

Each filter listed will respond to a network event that will trigger a system wake-up.

#defines

---

#define kIOEthernetMinPacketSize 64 

---

kIOEthernetWakeOnLANFilterGroup

---

kIOEthernetWakeOnLANFilterGroup describes the name assigned to the Ethernet wake-On-LAN filter group.

#define kIOEthernetWakeOnLANFilterGroup "IOEthernetWakeOnLANFilterGroup"
