We're looking at a deferred packet here, that's being allowed through,
presumably after the pfsync peer ack'd the state.

That should all just work, and I can't make it break in my test setup here.

It looks like you have a setup where the packet is getting forwarded to an
interface with a 9000 byte mtu, possibly after arriving on one with a 1500 byte
mtu. Does that sound familiar?

I think it's getting confused about the IP length somehow. Can you do a 'p *ip'
and 'p/x *ip' in frame 10? That should print the IP header and may contain more
clues.
