Merge branch 'add-tests-for-vxlan-with-ipv6-underlay' 

Amit Cohen says:

====================
Add tests for VxLAN with IPv6 underlay

mlxsw driver lately added support for VxLAN with IPv6 underlay.
This set adds the relevant tests for IPv6, most of them are same to
IPv4 tests with the required changes.

Patch set overview:
Patch #1 relaxes requirements for offloading TC filters that
match on 802.1q fields. The following selftests make use of these
newly-relaxed filters.
Patch #2 adds preparation as part of selftests API, which will be used
later.
Patches #3-#4 add tests for VxLAN with bridge aware and unaware.
Patche #5 cleans unused function.
Patches #6-#7 add tests for VxLAN symmetric and asymmetric.
Patch #8 adds test for Q-in-VNI.
