Subject: [net-config] Add support of connman's ServicesChanged signal
X-Git-Tag: submit/tizen/20160211.015108~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1271e68456599cf93009ad539ddfada9e66c6b10;p=platform%2Fcore%2Fconnectivity%2Fnet-config.git

[net-config] Add support of connman's ServicesChanged signal

Connman doesn't notify PropertyChanged signal if Property chage occurs
within 100ms, instead it notifies all  the Properties Changed in one
signal ServicesChanged. Due to this functionality in connman if ethernet
cable was plugged out and then plugged back in then ready state of
connman was not sent to net-config as sometimes connman state from
configuration to ready is changed in around 50ms.
This patch adds support of Connman's ServicesChanged signal in
net-config. net-config updates default connection info on receiving
ServicesChanged signal if there are no default connection available in
net-config at that time.
