446fe15067 Apply a bandaid to a problem elsewhere in the driver, when the process is
blocked in a write() while waiting for the output to drain, sleep only
for tp->t_timeout, not forever.  This only seems to happen when there is
either a modem lockup holding the hardware flow control down, or due to
some problem in the driver with processes attempting to write after the
modem has hung up (eg: elm, tf).

cba8a5ddd3 Make a "DWIM" function for adding [bc]devsw entries for bdev drivers.
Saves about 280 butes of source per driver, 56 bytes in object size
and another 56 bytes moves from data to bss.

No functional change intended nor expected.

76af5a923c Last night (local time :) I accidently checked in an intermediate version
of this patch, which had not actually been reviewed by Joerg or Paul!
(I'll better stop committing files after midnight ...)

I'm now commiting the latest code, which has been reported to work.

Minor correction to the previous commit message for this file:
The first PCI Lance in a system will get a name of lnc1, the second
will be known as lnc2 and so on. An arbitrary number of cards is
supported in a system ...

c268c94f6b FINALLY: PCI support for the Lance Ethernet driver.
This code applies to several systems with integrated Ethernet
chip, for example from HP or Compaq. It should also support
PCI Ethernet cards based on the AMD PCI Lance chip.

This code has been reviewed (visually) by Paul Richards and
tested (using an ISA Lance board) by Joerg Wunsch.
Since the parameters to nearly each and every single function
had to be changed (generally from unit number to lnc_soft*),
there is some potential for buglets having crept in ...

BEWARE: If you had lnc0 configured to have the ISA probe find
your PCI Lance, then it should now be found by the PCI probe,
and should be automatically configured as pci1 (!!! note the "1").

4611b39710 Enable transmit complete interrupt...
(author's explaination):

 Bit 15 is the flag to request a transmit complete interrupt.  The
driver was apparently written to minimize interrupts, and if not for a
3-COM design quirk, everything would be just ducky.
 Prior to loading the outbound packet into the FIFO, the driver checks
to see if there's enough space to contain the packet.  If not, the
driver requests a transmit-available interrupt when there is
sufficient room.  Unfortunately, the card is continuing to process the
prior FIFO, and by the time the driver sets the threshold for a
transmit available interrupt, the space is already available.  When
this occurs, the 3COM card ignores the interrupt request, and the
driver is hung waiting for an interrupt that will never occur.
There's probably a more elegant solution, but requesting the transmit
complete interrupt was the easiest to implement.  An alternative fix
might be to check free FIFO space again, after requesting the transmit
available interrupt, but I haven't bothered pursuing this.  Since the
patch, my 3C590 (PCI, same FIFO interface as 3C509) has been rock
solid.

d805b866fa This driver supports the SDL Communications RISCom/N2 ISA cards that is
based on the HD64570 chip. Both the 1 and 2 port cards is supported.

Line speeds of up to 2Mbps is possible. At this speed about 95% 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 X.21 interface is tested. The others may need
tweaks to the clock selection code.

7d64a7fe80 Added support for TIOCDCDTIMESTAMP (enable/get timestamp of last DCD rise).
Original version by John Hay.

Simplified timestamp code by reading the time exactly when necessary.
This may slow down the interrupt handler with extra calls to microtime(),
but only in bad configurations - the input fifo should normally be
disabled if timestamps on input are being used, since otherwise the
timestamp won't be precisely associated with any particular input event.
The interrupt handler remains slowed down by one test and branch for
each input (and now DCD change) event - avoiding this is not practical
yet.

The simplifications also fixed:
- timestamps for input sometimes being clobbered by output and modem
  status interrupts.
- valid timestamps not being available unless the port is configured with
  vector siointrts.  siointrts no longer exists.
- compiler warnings about siointr* in some configurations.

Simplified timestamp and probe code by depending on recent changes in
microtime() and DELAY() to preserve the interrupt enable flag.
