v3: Fixed Anderson and Luiz comments and solved rebased conflicts.
v2: Refactored profiles/network/common.* as per Johan's comments
(renaming common.c|h to bnep.c|h and moving bnep related code to
bnep.c ro reduce redundancy in profiles/netowrk/connection.c and
android/pan.c)
v1: This patch set supports PANU role with a minor fix in android. Added
CAP_NET_RAW capability for bnep services. Creates bnep connection and
up the inreface on connect call and free the device on disconnect call.
Interface name(bnepX) will be notified on control state cb. Android
environment will create IP address with dhcp calls.
Ravi kumar Veeramally (7):
profiles/network: Remove redundant code for bnep interface name
profiles/network: Refactor bnep connection setup functionality
profiles/network: Rename common.c|h to bnep.c|h
android/pan: Implement pan connect method in daemon
android/pan: Implement pan disconnect method in daemon
android/pan: Implement the get local role method in daemon
android: Add reasons for adding capabilites to process

Implements the PAN connect method in android daemon with PANU role
only. Setting up the bnep environment, adds connection and makes
bnep interface up are part of bnep_connect call. Notifies bnep
interface on control state call back and connection status on
connection state call back.

1.8.3.2
Moving bnep connection setup related functionality to common.c.
Provided bnep_connect call with bnep_connect_cb for status and
bnep interface name. It will be simple if someone want to utilize
this call otherwise they have to reimplement similar functionality
with minimal changes (e.g. android/pan).
