MDI_SetSpeedDuplex()

Force the link-state setting

Synopsis:

int MDI_SetSpeedDuplex  (mdi_t * mdi,
                        int PhyAddr,
                        intSpeed,
                        int Duplex)

Arguments:

mdi

A pointer to the mdi_t structure obtained from MDI_Register() or MDI_Register_Extended().

PhyAddr

The physical address of the physical layer device (PHY) for which the link is to be forced.

Speed

The bit rate, in megabits per second, at which the PHY should operate.

Duplex

The speed at which to operate. Choices are:

• half-duplex speed -- specify 0
• full-duplex speed -- specify 1.

Description:

The MDI_SetSpeedDuplex() function forces the link state to a specific setting instead of allowing link autonegotiation to occur.

Classification:

QNX Neutrino
