This is a driver for SMC's 91x series of Ethernet chipsets,
including the SMC91C94 and the SMC91C111. Say Y if you want it
compiled into the kernel, and read the file
Documentation/networking/smc9.txt and the Ethernet-HOWTO,
available from <http://www.tldp.org/docs.html#howto>.

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. If you want to compile it as a
module, say M here and read Documentation/kbuild/modules.txt.
