About Intel Tcc/TSN with PCIe lane connection

[BrucePai]

Hi ~

I would like to know some advanced knowledge about Intel TCC/TSN.

I have a motherboard with an I226 that can support Intel TCC/TSN.

I also saw from an Intel document that to make the TSN/TCC available (or optimized), it requires connecting the PCIe lane for the NIC to certain PCIe lanes (see the pic below).

My question is: What's the difference if it doesn't use these two lanes?

As far as I know, the TSN feature is still workable in that case, so what's the difference?

Thanks~!

the NIC using i226-IT (onboard)

the PCIe lane of the NIC is connect to  PCIe #1 , PCIe #2 rather than the 2 TSN-etherent
