I have been working on this patch to have libvirt optionally set static routes.
So I found the function that adds both IPv4 and IPv6 addresses to the bridge in virnetdev.c. I found that besides the virNetDevAddIPv4Address() there is also virNetDevCleanIPv4Address(). I patterned my virNetDevAddGateway() after the virNetDevAddIPv4Address() function.
What I am puzzled about is that it appears that nobody calls the Clear function. What don't I understand?
Probably it's there just for completeness of API. The thing that I find strange is that these functions include "IPv4" in their names, in spite of working just as well for IPv6. It's very likely that if I dig back through the blame history (which won't be simple since the code has been moved into different files), I'll find that I originally wrote it (I have a vague memory of it), but don't think I would purposefully add IPv4 to the names... :-/
It appears to me that the addresses and routes assigned to a bridge are all removed when the network is destroyed but otherwise remain.
