I've seen no hard limits on the number of devices (eth0, vlan0000, lo, etc) that
you can have in a system, but I'm curious if anyone knows any practical
limits?  Are there any linear searches (ie walk the device list) other than
one-time configuration and other non-critical path instances?

The reason that I ask is I'm considering a box with 1000+
VLAN devices... :)

Thanks,
Ben
