Subject: Changed ping behaviour (backwards compatible). If we don't have any data
X-Git-Tag: release-1.0pre2~67
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=e20e143f1e99bdc0a7d92e97da1bd0dc40e8a83b;hp=e20e143f1e99bdc0a7d92e97da1bd0dc40e8a83b

Changed ping behaviour (backwards compatible). If we don't have any data
to send, we don't need to check if the connection is still alive.
Furthermore, if we receive any kind of data from the other end, we know
it's alive, so we don't need to check it either. So, PING requests are
only sent if we send packets but there is no response.
