Hi Paulo,

I have pushed all patches except patch #3. "dun_gw: Add BlueZ 5 version" 
from Frédéric just added recently the definition for DUN_GW_UUID. 
Obviously, I needed to update your patches to use DUN_GW_UUID instead of 
DUN_UUID. The bluez4.c file also uses DUN_GW_UUID as identifier.

Thanks a lot,
daniel
