On slow systems ofproto/trace in combination with a recirculation ID
causes issues because the flow is evicted before the second packet
can reach it.
I.e:
"
Flow: recirc_id=0x2,ip,in_port=1,vlan_tci=0x0000,dl_src=f8:bc:12:44:34:b6,
dl_dst=f8:bc:12:46:58:e0,nw_src=1.1.2.92,nw_dst=1.1.2.88,nw_proto=47,
nw_tos=0,nw_ecn=0,nw_ttl=64
bridge("br0")
-------------
>>>> Recirculation context not found for ID 2 <<<<
Final flow: unchanged
Megaflow: recirc_id=0x2,ip,in_port=1,nw_frag=no
Datapath actions: drop
Translation failed (No recirculation context), packet is dropped.
"
Since eviction of the flows is not needed for the current logic,
add a time/stop to bypass the problem.
