+ Say Y to include support for the EtherNAT network adapter for the
+ CT/60 extension port. The driver works by polling instead of
+ interrupts, so it is quite slow.
+
+ This driver is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module will be called smc91x.
