Can PCIe Gen3 root complex support Gen4 PCIe Bridge switch device.

[er_rahulgupta90]

Scenario: Gen4 Bridge switch connected to Host system (gen3 root complex).

When I am checking the generation of the connected PCIe bridge[configured @Gen4], I am getting unknown speed/generation.

My understanding is that the root complex should be higher or equal [in generation] to PCIe switch bridge device to support all the speed/generation .

Please correct me if wrong.

Thanks
