Cheap Gigabit switch will allow DHCP thru it?

If your system has udev you might find a file with a name
something like /etc/udev/rules.d/z25_persistent-net.rules that
has entries something like this:

   SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:12:3f:57:4a:66", NAME="eth0"

...which can force the NIC with the specified MAC addr to be
assigned the specified interface name.  Just be sure that if
you arrange for an interface to get a new name you also ensure
that all config files that refer to that interface by the old
name are changed to reflect the new name.
