fe63158271 Changes to the Digi/Arnet SYNC driver:
1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
   With this change the speed as tested with ttcp on a 2Mbit link went up
   from 206kbyte/s to 236kbyte/s.
2. Change the rest of the functions to also have the definition of the
   return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.

(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
   are running at 2Mbit/s.

cc9fce5ad7 This driver supports the Arnet SYNC/570i ISA cards that is based on the
HD64570 chip. Both the 2 and 4 port cards is supported and auto detected.

Line speeds of up to 2Mbps is possible. At this speed about 85% of the
bandwidth is usable with 486DX processors.

The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.

At the moment only the V.35 and X.21 interfaces is supported. The others
may need tweaks to the clock selection code.

c5d1682b14 Staticized an inline function. All inlines in kernel headers should be
static.  The function shouldn't be here anyway.  It is driver dependent,
while `ic' files are supposed to only depend on the IC.

94ec1fba9a Rewrite:
- use pseudo-dma
- provide the same features and interface as sio
- support multiple boards
- fix bugs.

Some compile-time configuration constants are set to support higher
speeds and Cyclom-16Y's at a 30% relative cost in efficiency.
Cyclom-16Y support is untested.

e05407d84b New and far better NCR5380/NCR53400 scsi-driver.
Handles at least Trantor T130 and ProAudioSpectrum adapters.
The pas driver has consequently been removed.
This driver can be configured without without interrupts.

Manpage to follow when PAS16 has been edited in.

dc5df763e4 Peter's work to work around one of the most annoying bugs in the
floppy driver (or in the hardware?).  It turned out to be caused by
spurious interrupts, right after an FDC reset.

Also major cleanup in the low-level structure, there are now functions
performing error-checks for the FDC I/O.

cc6ed8bf5e (There's two of these now (Am7990.h and am7990.h) and they need to
be merged at some point)

New AMD family ethernet driver. Should support BICC,NE2100, TNIC,
AT1500 and anything else that uses a Lance/PCnet type chip. Only been
tested with the BICC so far though.

Still work to do on performance and MULTICAST support needs to be added
but it's basically working and I want the revision history from this
point on

3a2f7427fe Updated driver to the 1.1.5 version:
date: 1994/05/22 12:35:38;  author: joerg;  state: Exp;  lines: +6 -6
First round of floppy changes. Try making `fd' more robust.

New features:
  .  ioctl command for setting the drive type (density etc.); restricted
     to the super-user
  .  ioctl for getting/seting `drive options'; currently only option
     is FDOPT_NORETRY: inhibit the usual retries; used when verifying
     a newly formatted track

Fixes:
  .  function prototypes
  .  made all internal functions `static'
  .  cleaned up & corrected .h files
  .  restructured, to make the chaotic function sequence more rational
  .  compiled with -Wall, and cleared all warnings
  .  introduced a mirror for the (write-only) `digital output register',
     to avoid the current kludge
  .  device probing completed by seeking/recalibrating, and looking
     for track 0 being found
  .  holding the controller down in reset state while it is idle (and
     thus saving allot of headaches)
  .  make requests fail that are not a multiple of the (physical)
     sector size
  .  removed the fixed physical sector size (512 bytes), allowing for any
     size the controller could handle (128/256/512/1024 bytes)
  .  replaced some silly messages
  .  fixed the TRACE* macro usage, debugging reports should be complete
     now again (debugging output is HUGE! though)
  .  removed fd_timeout for SEEK command; seeks are always reported by
     the controller to succeed, since the `success' only refers to the
     controller's idea of success - there is no hardware line to tell about
     the seek end (other than the `track 0' line)
  .  catch SENSEI's that report about a `terminated due to READY changed'
     status - could happen after a controller reset
  .  converted ``hz / <something>'' divide operations to divisors that are
     powers of two, so gcc can optimize them into shifts
  .  write/format operations are checked against a write-protected medium
     now *prior* starting the operation
  .  error reports of `invalid command' and `wrong cylinder' will cause
     shortcuts in the retrier() now
  .  fixed a bug in the retrier() causing bogus block numbers to be reported
  .  fdformat() does care for errors now

Known Bugs:
  .  no attempts have been made (yet) to improve the performance
  .  sometimes, bogus ``seek/recalib failed'' messages are logged; this
     is still a bug in the driver, but it's not harmful since it's
     usually caught by the retrier()

e9d1679134 Added my ProAudioSpectum SCSI driver for cards with the 5380 SCSI-chip.
This is the slowest and most stupid of our SCSI-drivers, but it is there
and it works.  It has been tested with CD-ROM and disk.
It uses no interrupts, no DMA, just polled I/0.
Transfer-rate is <= 100Kbyte/sec.
If you set the jumpers on the board, you can change the unit-number and
you will be able to have four of these co-exist in one computer, why one
would do that is somewhat unclear though.
If I ever get my hand on the docs for this, I will improve it of course,
but for now we can install and access those CD-ROMs.

7952584606 New ethernet device driver from Matt Thomas:
This driver supports all the DEC EtherWORKS III NICs (DE203, DE204,
and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202,
DE422).  DEPCA-style boards prior to the DE200 have not been tested
and may not work.

775985234f This is the IBM/National PCMCIA ethernet driver from Keith Moore,
based originally on work by David Greenman and adapted to FreeBSD
(and cleaned up a bit) by myself.  It supports the IBM Credit Card
Adapter for the IBM Thinkpad, and I've had no trouble making it work
on my Toshiba T1910 with a National `InfoMover' NE4100 PCMCIA ethernet
card (I'm commiting this message through it right now :-).

This is actually sneaking it in after feature-freeze, but it's just
too useful to pass up!  As always, necessity is a mother.
