      Description

      After removing the external interface of a router no SNAT flows are removed.
      After removing of a router there are still flows on a compute node with the IP of the router.

      An example of flows:

      cookie=0x8000003, duration=6586.136s, table=21, n_packets=0, n_bytes=0, priority=42,ip,metadata=0x324b0/0xfffffe,nw_dst=10.0.0.214 actions=goto_table:25
      cookie=0x122201d9, duration=205.588s, table=81, n_packets=0, n_bytes=0, priority=100,arp,metadata=0x4157e000000/0xfffffffff000000,arp_tpa=10.0.0.214,arp_op=1 actions=move:NXM_OF_ETH_SRC[]>NXM_OF_ETH_DST[],set_field:fa:16:3e:9a:c9:20>eth_src,load:0x2->NXM_OF_ARP_OP[],move:NXM_NX_ARP_SHA[]>NXM_NX_ARP_THA[],move:NXM_OF_ARP_SPA[]>NXM_OF_ARP_TPA[],load:0xfa163e9ac920->NXM_NX_ARP_SHA[],load:0xa0000d6->NXM_OF_ARP_SPA[],load:0->NXM_OF_IN_PORT[],load:0x400->NXM_NX_REG6[],write_metadata:0/0x1,goto_table:220
