the lclassifier flow table 101 is like this:

cookie=0xf005ba1100000002, duration=3862.249s, table=101, n_packets=0, n_bytes=0, priority=500,icmp,in_port=5,nw_src=10.10.10.109,nw_dst=10.10.10.106 actions=push_nsh,load:0x1->NXM_NX_NSH_MDTYPE[],load:0x3->NXM_NX_NSH_NP[],load:0x44->NXM_NX_NSP[0..23],load:0xff->NXM_NX_NSI[],load:0xffffff->NXM_NX_NSH_C1[],load:0->NXM_NX_NSH_C2[],resubmit(,17)

When the vm hard reboot ,the inport is changed.  But the inport of the flow table is not changed.
