23a0ed7c08 Increased the number of Tx segments from 13 to 29 to reduce the need to
recopy to near zero. Wrote the necessary code to recopy the mbuf chain
into another buffer if there are too many mbufs in the chain.

4a5f1499b0 all:
Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.

if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.

if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).

d01b66804a A batch of Jim Lowe's patches:
o Add signed/unsigned functionality to the matrox meteor device driver.
	o Apply a few fixes to the sound driver.
	o Add a ``SPIGOT_UNSECURE'' compile time definition so, if one defines
	  SPIGOT_UNSECURE in their conf file, then they can use the spigot w/o
	  root.  There is a warning that this allows users access to the IO
	  page which is probably not secure.

point `ahc_pci_intr()' is used for PCI.  ISA and PCI interrupts are
penalized equally (:-) by calling a common handler `ahc_intr()'.  This
should be reorganized.  Some strings now name the wrong function...

eec7e07a40 Identify the 2940 *Ultra* SCSI adapter. We treat it as a normal 2940
for now since I don't have any documentation on this card yet and it

The 2940 *Ultra* is Adaptec's push to take SCSI to 20MHz bus rates.  Its
based on the aic7880 chip which is the successor to the aic7870.

8befc21fbd The NCR script has grown beyond one page (4KB). Since malloc() returns
contiguous memory in virtual space, but doesn't guarantee any particular
physical layout of pages, the script may be not contguous in physical
memory. This made the first write command fail in very rare cases.
This has been fixed by checking the region returned by malloc() for
being contiguous, but there should be a physical memory allocate
and later mapping to virtual memory instead.

A few assertions and error messages are improved.

07b1c6b3c9 Remove hard coded assumption that SCSI busses have 7 targets.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct.  Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal.  For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).

Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*.  This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

The devconf headers have convoluted interdependencies.  <sys/devconf.h>

drivers include <sys/devconf.h> so even isa drivers depend on
<pci/pcivar.h>.  For similar reasons, most drivers depend on another
pci header, on an isa header and on two scsi headers.

cb09d35cb0 Added a new field to the pci_device struct called pd_shutdown to specify
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.

Use pmap_mapdev().  Automatically map any large linear frame buffers

own drivers, and don't call not_supported() for them.  (This shuts up
complaints about my Matrox card.)  Include the beginnings of what could
eventually become dynamically-loadable PCI devices.  Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
