Description
===========
The DEFPA adapters provide 100 Mbits-per-second FDDI LAN connectivity for
any PCI V2.1-compliant host platform and are backward-compatible with any
PCI V2.0-compliant host platform. The DAS (Dual Attachment Station) options
can be connected as DAS, SAS (Single Attachment Station), or dual-homed
adapters. Both SAS and DAS options can operate in full-duplex mode (OFF by
default) when connected point-to-point with a cooperating full-duplex
adapter or FDDI switch.
