-  Some systems see lots of errors with NatSemi ethernet controllers
-  on certain cables.  If you are seeing lots of errors, try turning
-  this option on.  Some boards have incorrect values for supporting
-  resistors that can cause this change to break.  If you turn this

-  option off.

-  Say N unless you are certain you need this option.
-  Vendors should not enable this option by default.
