78534d41e1 Terminate negociation if Ext. link negociation succeeds. This avoids
the unknown mode panic during boot probe.

bc35c17446 Major ppbus commit with:
+ ECP parallel port chipset FIFO detection
	+ DMA+FIFO parallel I/O handled as chipset specific
	+ nlpt updated in order to use the above enhanced parallel I/O.
	  Use 'lptcontrol -e' to use enhanced I/O
	+ Various options documented in LINT
	+ Full IEEE1284 NIBBLE and BYTE modes support. See ppbus(4) for
	  an overview of the IEEE1284 standard
	+ Detection of PnP parallel devices at boot
	+ Read capability added to nlpt driver to get IEEE1284 compliant
	  printer status with a simple 'cat /dev/lpt0'
	+ IEEE1284 peripheral emulation added to BYTE mode. Two computers
	  may dialog according to IEEE1284 signaling method.
	  See PERIPH_1284 option and /sys/dev/ppbus/ppi.c

All this code is supposed to provide basic functions for IEEE1284 programming.
ppi.c and nlpt.c may act as examples.

46f3ff7986 Major ppbus updates from the author.
- ppbus now supports PLIP via the if_plip driver
 - ieee1284 infrastructure added, including parallel-port PnP
 - port microsequencer added, for scripting the sort of port I/O
   that is common with parallel devices without endless calls up and down
   through the driver structure.
 - improved bus ownership behaviour among the ppbus-using drivers.
 - improved I/O chipset feature detection

The vpo driver is now implemented using the microsequencer, leading to
some performance improvements as well as providing an extensive example
of its use.

3f2076daf5 Make the debug options new-style.
This also zaps a DPT option from lint; it wasn't referenced from
anywhere.

e51b0386a6 Sync with ppbus-970815 from the author :
- interrupt-driven printing now works (nlpt)
 - Rearrangement of bus-related functions into ppb_base/ppbconf
 - Addition of ieee1284 interface functions, preliminary parallel-port
   PnP support
