Include support for the LAN OSM. You will also need to include
support for token ring or FDDI if you wish to use token ring or FDDI
I2O cards with this driver.
This support is also available as a module called i2o_lan ( = code
which can be inserted in and removed from the running kernel
whenever you want). If you want to compile it as a module, say M
