description:
if the PCI_CONFIG_DUMP option is defined, set the patchable
pci_config_dump variable to 1.  otherwise, it gets set to 0.  If
that's set, when configuring PCI devices spew the very verbose
configuration space header dump that was previously "#if 0"'d.
If you use this option, or patch the variable to 1, it's strongly
encouraged that you have used the MSGBUFSIZE option to enlarge the
kernel message buffer.
