Bug Description

konversation disconnects the connection to an irc server after every dhcp renewal with connman. I checked with this tcpdump, the tcp connection is closed immeadiately (max 100 ms) after dhcp ack from the server.

The problem was that connman reset the settings during every dchp renewal, even though there were no actual changes in the dhcp settings. konversation again has some logic to detect address changes, and this caused the disconnections from the server.

I sent an rfc patch to upstream:

Daily builds also now have my rfc patch. This will be fixed in upstream once the element refactoring is finished, which will most likely take few weeks.
