Add Ethernet Expansion Card support for the framework laptop. Due to automatic USB device suspension, the Ethernet Expansion Card was not working. Adding a udev rule to only suspend the card after 20 seconds fixes the problem. The framework support confirmed via email that all current Ethernet Expansion Cards share the same Product ID.
