Hi

Attached patch makes it possible to use a configuration in hcid.conf
for a device with a certain Bluetooth device address:

   options
   {
	# hcid options...
   }

   device
   {
	# Default device options...
   }

   device 00:11:22:33:44:55
   {
	# Device options for bdaddr 00:11:22:33:44:55...
   }

It's useful to do persistent device specific configurations, for example
setting unique and meaningful names. I've only done limited testing.

Any thoughts?

Fredrik
