Most of the limits on the number of any device come from the major/minor 
numbers on the device nodes.  Since ethernet adapters don't have device 
nodes, I'd be surprised if there were any practical limit.

I'm able to create at least 1025 VLANs on my ethernet adapter, and VLANs 
are "real" interfaces in the kernel.
