svn commit: r219865 - head/sys/dev/pci

[John Baldwin]

Author: jhb
Date: Tue Mar 22 12:05:49 2011
New Revision: 219865
URL: http://svn.freebsd.org/changeset/base/219865

Log:
  Rename pci_find_extcap() to pci_find_cap().  PCI now uses the term
  "extended capabilities" to refer to the new set of capability structures
  starting at offset 0x100 in config space for PCI-express devices.  For now
  both function names will still work.  I will merge this to older branches
  to ease driver portability, but 9.0 will ship with a new pci_find_extcap()
  function that locates extended capabilities instead.
