c36c6e72c6 Various updates to the PCI-express capability output.
- Group the output so that it follows the capability register set more
  closely.  The first line now contains device information and the
  second line contains link information.  As a result, ARI status is now
  output on the first line, and the link width is moved down to the second
  line of link information.
- Only read the DEVICE_CAP2 register to check for ARI if the capability
  version is >= 2.
- Don't output any link information if the link capability and status
  registers are zero.
- Label the MSI interrupt index value as "MSI" instead of "IRQ".

a28a4d77b6 Fix possible out-of-bounds access detected by Ulrich Spörleins "scan-build".
Some invalid PCI device selectors could cause read access to an initialized
variable next to the array (local loop index variable).

While here, the parser has been made more strict with regard to the syntax
of PCI device selectors as documented in the man-page. E.g. "pci:" used to
be interpreted as "pci0:0".

15d107308f Add a new -B flag for use with list mode (-l) that lists details about
bridges.  Currently this includes information about what resources a
bridge decodes on the upstream side for use by downstream devices including
bus numbers, I/O port resources, and memory resources.  Windows and bus
ranges are enumerated for both PCI-PCI bridges and PCI-CardBus bridges.

To simplify the implementation, all enumeration is done by reading the
appropriate config space registers directly rather than querying the
bridge driver in the kernel via new ioctls.  This does result in a few
limitations.

First, an unimplemented window in a PCI-PCI bridge cannot be accurately
detected as accurate detection requires writing to the window base
register.  That is not safe for pciconf(8).  Instead, this assumes that
any window where both the base and limit read as all zeroes is
unimplemented.

Second, the PCI-PCI bridge driver in a tree has a few quirks for
PCI-PCI bridges that use subtractive decoding but do not indicate that
via the progif config register.  The list of quirks is duplicated in
pciconf's source.

  guaranteed to be ASCII values (though most are).
- Add a new pciio ioctl to fetch VPD for a single PCI device.  The values
  are returned as a list of variable length records, one for the device
  name and each keyword.
- Add a new -V flag to pciconf's list mode which displays VPD data for

389c8bd51e Align the PCI Express #defines with the style used for the PCI-X
#defines.  This also has the advantage that it makes the names more
compact, iand also allows us to correct the non-uniform naming of
the PCIM_LINK_* defines, making them all consistent amongst themselves.

This is a mostly mechanical rename:
  s/PCIR_EXPRESS_/PCIER_/g
  s/PCIM_EXP_/PCIEM_/g
  s/PCIM_LINK_/PCIEM_LINK_/g

When this is MFC'd, #defines will be added for the old names to assist
out-of-tree drivers.
