I googled a bit 
Apparently those packages are garbage and will never reach it's destination anyway. There was a problem in 2.6.28 with some NIC and multicast.
What kernel and nic do you use? If it is one of the default gentoo sources, you probably want to file a bug report.

What kind of machine is this? A router or something? As I read this can be caused by p2p software, it drops packages it cannot route and leaves a log.
If you have control over all the software, try to find out what produces those packages.
Especially if it happened suddenly yesterday, it is not likely to be a bug if you didn't change much.
