I'm a bit confused with this bit wrt to what actually happens later in the
code. Basically this @ipsock is only relevant up until the point where we start
registering services listening for traffic e.g.virNetServerAddServiceTCP (this
is one is easier as an example). If I look at the condition:
if (((ipsock && config->listen_tcp) || act) ...
why does it even matter that we clear ipsock when socket activation is enabled?
The condition is true regardless of @ipsock and it's also not populated further
into the function being called unlike @act, so this bit is making me confused,
so what exactly is happening if we don't clear @ipsock with virtproxyd?
