[PATCH 0/15] Implement DUN server in oFono

[Zhang, Zhenhua]

Hi,

[Fix misleading title and content in previous 0/15 mail. Sorry for that.]

This series are based on the previous 6 patches "Add oFono DUN emulator" sent on July 5th. It implements the main functionality of DUN server and interact with GPRS atom to create DUN context. You can use gatchat/test-emulator to create a pseudo terminal and then use gsmdial to create a DUN client connection. 

Regards,
Zhenhua
