nit: CastUdpSocketFactory to be consistent with CastUdpTransport.

[hubbe, 2013/11/26 20:24:29]

Done.

This should be scoped_ptr<content::P2PSocketClient>.

[hubbe, 2013/11/26 20:24:29]

scoped_refptr actually

+    return socket;

[Alpha Left Google, 2013/11/09 00:30:18]

return socket.Pass() if socket is a scoped_ptr.

[hubbe, 2013/11/26 20:24:29]

using scoped_refptr, no need for Pass

Might as well just change the type to net::IPAddressNumber in this change. It's
not a lot of affected code locations.

[hubbe, 2013/11/26 20:24:29]

Done.
