Hi, i have a VM with ARP entries in both OpenVswitch bridges br-tun and 
br-int on the compute node where is it executed:

     ovs-ofctl dump-flows br-int | egrep "arp.*10.20.0.34"
     cookie=0x117c25cd8a3f96, duration=47029.368s, table=24, 
n_packets=20, n_bytes=840, 
priority=2,arp,in_port="qvod9cdff27-9c",arp_spa=10.20.0.34 
actions=resubmit(,25)

     ovs-ofctl dump-flows br-tun | egrep "arp.*10.20.0.34"
     cookie=0x1597c76aa2fd74f2, duration=47015.961s, table=21, 
n_packets=0, n_bytes=0, priority=1,arp,dl_vlan=27,arp_tpa=10.20.0.34 ... 
3e:42:af:1d,IN_PORT

The unnecassary / faulty entry can by deleted manually from br-tun with:

     ovs-ofctl --strict del-flows br-tun 
"priority=1,arp,dl_vlan=27,arp_tpa=10.20.0.34"

but after the port is shutdown and up again the entry will by recreated 
again. When the VM is moved to another compute node, only the br-int 
entry is created, moving back to the initial host creates both again.

Any idea how to remove permamenty this br-tun entry?

Thanks
Pawel
