What is wrong with USB network devices?  The USB3 ones can even do
Gigabit and they work well.

A router/firewall has to process lots od small packets where latency is 
more of an issue than raw transfer rates.   USB3 is much better than 
USB2, but there are still extra function calls and you are relying on 
the quality of the USB3 drivers as well as the ethernet driver.  Most
reviews of USB3 ethernet devices only consider a desktop role, so 
may not reflect suitability for router/firewall service.
