287911bd50 Go back to separate tests for configuration mechanism 1 and mechanism 2. 
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.

The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.

77b573149a New approach to the PCI bus configuration mechanism probe problem: 
- try to make sure there is any kind of PCI device
- if there is anything at port 0x0cf8, then check for mech. 1 or 2

a3adc4f8c5 Revert most changes of previous commit. 
Changes relative to 1.12:
- Put extra instruction between outl()/inl() sequence to prevent the
  old value being read back because of the bus capacitance.
- Additional check for existence of register at CONF2_ENABLE_PORT.

2d14418625 Another try to determine the PCI bus configuration mode (and whether 
there is a PCI bus at all) ...

- Do not expect the chip sets to follow even very clearly expressed
  requirements of the PCI 2.0 spec.
- Do not read back the value just written to an I/O port without making
  sure that some other data have crossed the bus in between ...

0847c06d2e PCI configuration mechanism now determined by a method, that doesn't 
fail on new hardware (Compaq Prolinea and Compaq Prosignea), and that
doesn't erroneously identify old mech. 2 chip sets as using mech. 1.

d33095d2b2 The physical memory allocated for input DMA must be contiguous. The driver 
worked in the past only because of good fortune. Anyway, use the contig alloc
routine I wrote awhile ago (vm_page_alloc_contig) for the sound code to do
this allocation. Also, specify read+write on the permissions to pmap_enter().
Specifying just read can have unexpected consquences.

307d80be7a Moved conversion of ether_type to host byte order out of ethernet drivers 
and into ether_input(). It was silly to have bpf want this one way and
ether_input want it another way. Ripped out trailer support from the few
remaining drivers that still had it.

b83f4f55d8 Bunch of fixes from Matt Thomas: 
1) make #includes correct
2) fix bugs in address check macros
3) fixed bugs in, and enabled, recopy if heavily fragmented code
4) moved call to bpf tap to be before enqueing packet (probably gratuitous)
5) fixed bug that caused "abnormal interrupt" at boot time/first use
6) added support for reading Zynx address ROM
7) fixed bug that caused broadcasts to not work shortly after booting (only
	manifested if not using multicast - e.g. not in FreeBSD 2.0)
8) fixed spelling errors in comments

f86233fe54 Added a bit of missing functionality to make this work correctly on a 
wider variety of systems.  Include the deivers from pci_intel.c in
pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev().  Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
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.
Make autoconfiguration text conform more to the style of other supported
buses.
