Inconsistency in underlay v6 support

[vmytnykx]

VNET-to-VNET doc (Overview section) says that underlay v6 should be supported. While BMv2 pipeline doesn't expect to receive v6 packets (for instance VIP table). So, there is an issue in doc about underlay v6 support or there is an issue in BMv2 pipeline.

Does DASH expect that underlay v6 should be supported also, for example VIP v6, IPv6 routing, etc. ?

VIP table declaration: https://github.com/Azure/DASH/blob/main/dash-pipeline/bmv2/dash_pipeline.p4#L38
Vnet Overview doc: https://github.com/Azure/DASH/blob/main/documentation/vnet2vnet-service/vnet-to-vnet-service.md#overview

Eventually both will be supported, it is a question of effort.
