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.
