After talking with Thunderbolt maintainers, TGL has still a firmware
based TBT Connection Manager implementation, contained in the BIOS/IFWI
image. The BIOS/IFWI version on the above host is rather old:

Intel(R) Client Systems NUC11TNHi5/NUC11TNBi5, BIOS TNTGL357.0042.2020.1221.1743 12/21/2020

So, could the CI team check if there is a new BIOS/IFWI available and
upgrade to it?

Thanks,
Imre
