It is. Has also infected the last two Ubuntu LTS releases and probably
jessie.
I have done some testing. It's unrelated to OpenVPN, it's the
combination of ethernet bridging and sungem. Bug occurs if you bridge a
sungem interface with anything. Other network chips bridge fine with
each other in the same machine with otherwise identical configuration.
The bridge will send packets through the sungem interface into the
network with no trouble, and will receive broadcast and multicast
packets from it, but unicast packets received through the sungem
interface don't make it to the bridge. So it may be that promiscuous
mode is broken.
