data path not working with Trunk port configuration. Packet getting dropped at table 214

Configuration:

Consider the following topology for testing trunk/subport use-case in dual stack network.

1) 3 networks and 3 ipv4 and 3 ipv6 subnets

openstack network create net0
openstack network create net1
openstack network create net2

 
neutron subnet-create net0 10.1.0.0/24 --enable-dhcp --name subnet0_IPV4
neutron subnet-create net1 11.1.0.0/24 --enable-dhcp --name subnet1_IPV4
neutron subnet-create net2 12.1.0.0/24 --enable-dhcp --name subnet2_IPV4

openstack subnet create --network net0 --subnet-range 2001:db8:0:3::/64 subnet0_IPV6 --ip-version=6 --ipv6-address-mode=slaac --ipv6-ra-mode=slaac
openstack subnet create --network net1 --subnet-range 2001:db8:0:4::/64 subnet1_IPV6 --ip-version=6 --ipv6-address-mode=slaac --ipv6-ra-mode=slaac
openstack subnet create --network net2 --subnet-range 2001:db8:0:5::/64 subnet2_IPV6 --ip-version=6 --ipv6-address-mode=slaac --ipv6-ra-mode=slaac

2) 3 ports on different subnet sharing same Mac-address

openstack port create --network net0 port0
openstack port create --network net0 normal-port
parent_mac="$( openstack port show port0 | awk '/ mac_address / { print $4 }' )"
echo $parent_mac
 

openstack port create --network net1 --mac-address "$parent_mac" port1
openstack port create --network net2 --mac-address "$parent_mac" port2

3) Configuring port0 as trunk and port1 and port2 as sub-ports.

openstack network trunk create --parent-port port0 trunk0
 
openstack network trunk set --subport port=port1,segmentation-type=vlan,segmentation-id=101 trunk0
openstack network trunk set --subport port=port2,segmentation-type=vlan,segmentation-id=102 trunk0

4) Create Router and add all IPv4/IPv6 subnets to router.

openstack router create router1
openstack router add subnet router1 subnet0_IPV6
openstack router add subnet router1 subnet1_IPV6
openstack router add subnet router1 subnet2_IPV6
openstack router add subnet router1 subnet0_IPV4
openstack router add subnet router1 subnet1_IPV4
openstack router add subnet router1 subnet2_IPV4

5) VM booted on trunk port.

openstack server create --flavor ds1G --availability-zone nova:osc-pike-ubuntu16 --image ubuntu --nic port-id=port0 VM1

openstack server create --flavor ds1G --availability-zone nova:osc-pike-ubuntu16 --image ubuntu --nic port-id=normal-port VM1

Validate data path between normal port to trunk port.

6) Create sub interface(VLAN) on booted ubuntu VM using below commands.

vconfig add ens3 101(Same as sub-port VLAN ID)
