IPv6 routing is not working with BVI interface

[bendrapubalareddy]

Host A ipv6 in subnet A--------Access - 802.1Q BVI in subnet A -SONiC VPP Bridge- 802.1q BVI in subnet B - Access----------HostB ipv6 host in subnet B

Host A sends NS to resolve ND entry , but SONic VPP bridge responds with NA with 802.1q tag which host A is not aware as, Host A is connected on access port of Bridge.

Same case works with IPv4. For IPv6 case, it's looking like, when packet is arrived on bridge access interface, it pushes 1q tag and sends to BVI interface for NA. ND stack responds with NA by adding another tag and send it to access port.

Traces on bridge access interface shows that there two tags on the packet when received by bridge access port.
