CONFIG_NATSEMI_CABLE_MAGIC
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 on and your network suddenly stops working, turn this
option off.
Say N unless you are certain you need this option.
Vendors should not enable this option by default.

If you have a network (Ethernet) card of this type, say Y and read
