Remove support for FDDI networks.

Browse source 
Defines in net/if_media.h remain in case code copied from ifconfig is in
use elsewere (supporting non-existant media type is harmless).

****************************** SPECIAL WARNING: ******************************
20180411:
Support for FDDI networks has been removed. If you have device
fddi or device fpa in your kernel config file they must be
removed.
20180406:
In addition to supporting RFC 3164 formatted messages, the
syslogd(8) service is now capable of parsing RFC 5424 formatted

.Sh NAME
.Nm fpa
.Nd device drivers for DEC FDDI controllers
.Sh SYNOPSIS
.Cd "device fpa"
.Pp
.Fx
only:
.Cd "device fddi"
.Sh DEPRECATION NOTICE
The
.Nm
driver is not present in
.Fx 12.0
and later.
.Sh DESCRIPTION
The
.Nm
device driver provide support for the DEC DEFPA PCI FDDI Controller.
All variants of the
controller are supported including the DAS and SAS configurations.
.Sh SEE ALSO
.Xr arp 4 ,
.Xr netintro 4 ,
.Xr ifconfig 8
.Sh AUTHORS
The
.Nm
device driver and this manual page were written by
.An Matt Thomas .
.Sh CAVEATS
Normally, the device driver will not enable the reception of SMT frames.
However if the IFF_LINK1 flag is set, the device driver will enable the
reception of SMT frames and pass them up to the Berkeley Packet Filter for
processing.
