Has the tag rule option changed in 2.0?  In particular should "tag: 
host, packets, 300, src" still work?  It looks like the src and dst 
attributes are no longer functioning.  My testing shows that tag host 
really means tag host src AND dst regardless of which (src or dst) you 

Second question?  How does tagging interact with stream reassembly?  My 
testing shows tagged packets getting logged twice, first individual 
packets and then again as one packet, presumably from stream reassembly.  

I have found the packet tagging to be an extremely useful feature.  I 
use it extensively to capture packets after a particular attack so that 
I can determine the success of the attack.
