Store the active media type for PhyAddr

Synopsis:

int MDI_GetActiveMedia ( mdi_t * mdi,
                       int PhyAddr,
                       int *Media)

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).

Media

A pointer to the media-type specified. Possible media types are:

• MDI_10bT -- 10 Base T, half-duplex
• MDI_10bTFD -- 10 Base T, full-duplex
• MDI_100bT -- 100 Base T, half-duplex
• MDI_100bTFD -- 100 Base T, full-duplex
• MDI_1000bT -- 1000 Base T, half-duplex
• MDI_1000bTFD -- 1000 Base T, full-duplex.

Description:

The MDI_GetActiveMedia() function stores the curently active media-type for the PHY that the media address specifies.

Returns:

MDI_BADPARAM

PhyAddr is out of range.

MDI_LINK_DOWN

No valid link was detected.
