Detailed Description

Class abstraction for Ethernet PHY interface customization.

The tcDspNetPhy class provides a common, extensible interface to ethernet PHY devices. This class allows handling of PHY specific control and status gathering via (by default) an provided MDIO interface or may be extended to use other interface mechanisms to provide similar capability.

Control over PHY specific features such as VLAN configuration, link parameter modification, etc., is achieved through this interface.

Constructor & Destructor Documentation

tcDspNetPhy::tcDspNetPhy ( void *  apAddress )

protected

Basic tcDspNetPhy constructor. This function creates the Phy interface class and initializes thread safe mutex's for it.

Parameters:

[in]

apAddress

the base address of the associated tcNetDrvr MityDSP FPGA interface

tcDspNetPhy::~tcDspNetPhy ( )

protected

Destructor. Typically not reached.

Member Function Documentation

tcDspNetPhy * tcDspNetPhy::GetSpecificPhy ( void *  apAddress )

static

PHY controller object factory. This is a static method that may be used to construct a specific PHY interface class that supports all of the features of the PHY. If no custom interface class is found for the detected PHY type, then a basic tcDspNetPhy object is returned.

Parameters:

[in]

apAddress

the base address of the associated tcNetDrvr MityDSP FPGA interface

Returns:

pointer to a tcDspNetPhy (or derived) controlling object

teNetPhyType tcDspNetPhy::GetPhyType ( unsigned int  anPhyAddr = 0xFFFFFFFF )

virtual

This routine is used to get the type of PHY in use.

Returns:

Enumeration representing one of the known PHY types, or eePhyUnknown.

unsigned int tcDspNetPhy::PhyProbe

(

)

This routine probes for valid MII manufacturer registers.

Returns:

Returns register offset (default: 1)

bool tcDspNetPhy::LinkUp ( unsigned int  anPhyAddr = 0xFFFFFFFF )

virtual

This routine returns whether or not the ethernet link is up. Register.

Returns:

Boolean indicating whether or not link is up.

Reimplemented in tcDspPhyMicrelKS8995.

unsigned short tcDspNetPhy::GetMIIRegister ( unsigned int  anRegAddr, unsigned int  anPhyAddr = 0xFFFFFFFF  )

virtual

This routine is used to read the current value stored in an MII Register.

Parameters:

[in]	anRegAddr	The offset to the desired MII register
[in]	anPhyAddr	The address of the PHY (default:0)

Returns:

MII Register contents.

int tcDspNetPhy::SetMIIRegister ( unsigned int  anRegAddr, unsigned int  anValue, unsigned int  anPhyAddr = 0xFFFFFFFF  )

virtual

This routine is used to set the specified 16-bit value to an MII Register.

Parameters:

[in]	anRegAddr	The offset to the desired MII register
[in]	anValue	Value to write to the register.
[in]	anPhyAddr	The address of the PHY (default:0xFFFFFFFF)

Returns:

0.

bool tcDspNetPhy::GetPhyStatus ( tsNetPhyStatus &  arPhyStatus, unsigned int  anPhyAddr = 0xFFFFFFFF  )

virtual

Get the basic PHY status of a connected device from the standard MII status word.

Note:

the speed and duplex status cannot be determined from a base MII status word and are left at Unknown.

Parameters:

[out]	arPhyStatus	structure to update
[in]	anPhyAddr	address of the Phy (or 0xFFFFFFFF to probe)

Returns:

true if successful

Reimplemented in tcDspPhyMicrelKS8995, tcDspPhyBroadcomBCM5221, tcDspPhyCrystalLanCS8952, and tcDspPhyNational83848.

virtual const char* tcDspNetPhy::GetPhyName ( void  )

inlinevirtual

Reimplemented in tcDspPhyMicrelKS8995, tcDspPhyBroadcomBCM5221, tcDspPhyCrystalLanCS8952, and tcDspPhyNational83848.

virtual bool tcDspNetPhy::Initialize ( void  )

inlinevirtual

This method is called by a tcDspNetdrvr instance while opening the EMAC interface for use. This routine should return true if there are no errors. Classes should re-implement this if specific MDIO or other intialization commands are necessary prior to operation of the device.

Returns:

true on success

Reimplemented in tcDspPhyMicrelKS8995, tcDspPhyBroadcomBCM5221, tcDspPhyCrystalLanCS8952, and tcDspPhyNational83848.
