This is a driver for the FORE Systems 200E-series ATM adapter
cards. It simultaneously supports PCA-200E and SBA-200E models
on PCI and SBUS hosts. Say Y (or M to compile as a module
named fore_200e) here if you have one of these ATM adapters.
Note that the driver will actually be compiled only if you
additionally enable the support for PCA-200E and/or SBA-200E
cards.
See the file <file:Documentation/networking/fore200e.txt> for
further details.
