Since this rule is so weak, I think the priority should be set to 250 just so it is run after any other possible matches.

Could we also add a check that if the value of data->payload[x] < 1400, then it must match data->payload_size[x]? Or can small records still be spread across multiple packets?
Just trying to think of ways where we can rule out certain payload patterns that might just happen to be on port 88 -- very unlikely, I know, but anything to make this rule seem a bit stronger...
