* DEC PDQ FDDI Controller; code for BSD derived operating systems

* This driver supports the following FDDI controllers:
*
* Device: Config file entry:
* DEC DEFPA (PCI) device fpa0
* DEC DEFEA (EISA) device fea0 at isa0 net irq ? vector feaintr
*
* Eventually, the following adapters will also be supported:
*
* DEC DEFTA (TC) device fta0 at tc? slot * vector ftaintr
* DEC DEFQA (Q-Bus) device fta0 at uba? csr 0?? vector fqaintr
* DEC DEFAA (FB+) device faa0 at fbus? slot * vector faaintr
