What is meant by "Native Interfaces" in regards to the Thunderbolt 4 Controller (Intel JHL8440)?

The Intel JHL8440 Thunderbolt 4 Controller Product Specifications, at: https://ark.intel.com/content/www/us/en/ark/products/189982/intel-jhl8440-thunderbolt-4-controller.html states the following:

Supplemental Information:

Description:

+ Thunderbolt/USB4 peripheral support at 40G

+ Native USB Type-C interface capabilities: USB2, USB3 (10G), DP1.4 Alt-mode

+ Tunneling capabilities (32G PCIe, USB3(10G), 2 displays (up to DP1.4)

+ Other native interfaces: x1 PCIe 8GT/s, 1x USB3 (10G)

I am looking for clarification of the following:

1) Native USB Type-C interface capabilities:  USB2,  USB3 (10G),  DP1.4 Alt-mode

-and-

2) Tunneling capabilities (32G PCIe ...

-and-

3) Other native interfaces:  x1 PCIe 8GT/s,  1x USB3 (10G)

-> Does "x1 PCIe 8GT/s" mean that this Thunderbolt 4 controller only supports one (1) PCIe 3.0 lane in the "link" to / from the Thunderbolt 4 Host controller (Intel JHL854) ?

-> If not, what is meant by the reference "x1 PCIe 8GT/s" ?

-> Is the data carried by the "x1 PCIe 8GT/s" Thunderbolt 4 Native Interface the same -or- included in the 32Gb/s carried in the tunneling of Thunderbolt 4?

-> Is the 1x USB3 (10G) data, referenced as Native Interface, carried by the Thunderbolt 4 tunneling -or- by the "Data+" and "Data-" pins defined as USB-C Pins "A6 and B6" plus "A7 and B7"?

-> Are the Native USB Type-C interface capabilities: USB2, USB3 (10G), DP1.4 Alt-mode carried by the Thunderbolt 4 tunneling -or- by the "Data+" and "Data-" pins defined as USB-C Pins "A6 and B6" plus "A7 and B7"?

Thank you, in advance, for your time and assistance with addressing my questions.

Which “community support case” are you closing?

Does your reply mean thatI I can have only one (1) question posted on the Intel Community?
