Subject: udev/hwdb support in pciutils (Re: [PATCH RESEND][pciutils] libpci:
 pci_id_lookup - add udev/hwdb support)

Hi Tom!

The support for hwdb has finally landed in mainline pciutils.

I have modified your patch to bring it closer to the rest of device
naming logic. Namely:

  •  The interface to HWDB now lives in a separate source file
     lib/names-hwdb.c. It is called from the main entry point
     to the name resolver (lib/names.c).

  •  Resolved names are cached in the hash table and they participate
     in the system of priorities. They have lower priority than pci.ids,
     but higher than remote lookups via DNS. (Therefore if a distro
     decides not to ship pci.ids, hwdb is used exclusively for all
     local lookups.)

  •  There is a flag to suppress the use of HWDB (PCI_LOOKUP_NO_HWDB)
     and also a configuration parameter for the same (hwdb.disable).

Aside of the README, everything should be ready for a public release.
Could you please verify that it still works for you?

				Have a nice fortnight
