Comment 1 for bug 1912651

Confirmed, I could reproduce this bug. After restart the openvswitch (ovs-db and vswitchd), these types of flows lost:
table=82, priority=70,ct_state=+est-rel-rpl,ipv6,reg6=0x3,ipv6_src=[*] actions=conjunction(*,1/2)
table=82, priority=70,ct_state=+new-est,ipv6,reg6=0x3,ipv6_src=[*] actions=conjunction(*,1/2)

table=82, priority=70,ct_state=+est-rel-rpl,ip,reg6=0x3,nw_src=[*] actions=conjunction(*,1/2)
table=82, priority=70,ct_state=+new-est,ip,reg6=0x3,nw_src=[*] actions=conjunction(17,1/2)
