SD-VPN:L3 service: more than 1 sub interface (IP-UNI) on a port - rules are created only for the 1st one

add a tenant with a L3 service:
1CPE - add more than 1 sub interface (IP-UNI) on each port
sending traffic between the ports interfaces fails

looking at the rules in table 21 i see a rules only for the 1st sub interface (IP-UNI) from each port

example:
on ens5
1111 10 110.1.1.1/29
1112 11 110.1.1.9/29

on ens6
1121 10 110.1.2.1/29
1122 11 110.1.2.9/29

associated UNIs
CE 1 ens5 110.1.1.9/29 11
CE 1 ens6 110.1.2.9/29 21
CE 1 ens5 110.1.1.1/29 10
CE 1 ens6 110.1.2.1/29 20
