This typedef is the repeater topology table used to communicate topology information to the receiver upstream interface.
| u8 XHdcp22_Rx_Topology::Depth |
Repeater cascade depth.
This value gives the number of attached levels through the connection topology with maximum depth of 4.
Referenced by XHdcp22Rx_Info().
| u8 XHdcp22_Rx_Topology::DeviceCnt |
Total number of connected downstream devices.
Always zero for HDCP Receivers. This count does not include the HDCP Repeater itself, but only devices downstream from the HDCP Repeater.

| u8 XHdcp22_Rx_Topology::Hdcp1DeviceDownstream |
Flag used to indicate topology information.
When set to one, indicates precense of an HDCP1.x-compliant device in the topology.

| u8 XHdcp22_Rx_Topology::Hdcp2LegacyDeviceDownstream |
Flag used to indicate topology information.
When set to one, indicates presence of an HDCP2.1-compliant Device in the topology.

| u8 XHdcp22_Rx_Topology::MaxCascadeExceeded |
Flag used to indicate topology error.
When set to one, more than four levels of repeaters have been casaded together.

| u8 XHdcp22_Rx_Topology::MaxDevsExceeded |
Flag used to indicate topology error.
When set to one, more than 31 downstream devices are attached.

| u8 XHdcp22_Rx_Topology::ReceiverIdList[31][5] |
Receiver ID list of all downstream devices.
The list consists of a contiguous set of bytes stored in big-endian order, with each Receiver ID occuping five bytes and a total of 31 Receiver IDs.
