Detect Ethernet link state.

unsigned int BIOS_Ethernet_State ( unsigned int *init_error,
                                   unsigned int *phy_state );

Parameters

init_error

non-zero indicates initialization or reset procedure of Ethernet device failed.

phy_state

SC13/SC1x3/SC2x only: phy status
Bit 14          1 = Link Not detected
Bit 07          1 = 100Base-TX mode, 0=10Base-T mode
Bit 06          1 = Device in Full Duplex mode

Return Value

non-zero indicates have no Ethernet link.

Comments

If return value is non-zero (no Ethernet link), this may be due to the network cable not being connected.
In the SC12, a zero is output to phy_state.
