I'm looking into it which classifier? A basic u32 classifier attached
to the ingress qdisc seems to work. If your using u32 any hash tables,
or 'filter change' commands before this?

# tc actions add  action drop index 4

# tc filter add dev p3p1 parent ffff:0 protocol ip prio 100 \
	u32 match ip src 16.0.0.2 action gact index 4

#tc -s actions ls action gact

         action order 0: gact action drop
          random type none pass val 0
          index 4 ref 2 bind 1 installed 142 sec used 0 sec
         Action statistics:
         Sent 840 bytes 10 pkt (dropped 10, overlimits 0 requeues 0)
         backlog 0b 0p requeues 0
