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.

Spectrum ASICs do not support matching of VLAN ID at egress.
Currently, mlxsw driver forbids matching of all VLAN related fields at
egress, which is too strict check.
For example, the following filter is not supported by the driver:
$ tc filter add dev swpX egress protocol 802.1q pref 1 handle 101 flower
vlan_ethtype ipv4 src_ip .. dst_ip .. skip_sw action pass
Error: mlxsw_spectrum: vlan_id key is not supported on egress.
We have an error talking to the kernel
The filter above does not match on VLAN ID, but is bounced anyway.
Make the check more specific, forbid only matching of 'vlan_id' at egress.

Currently `ping_do()` and `ping6_do()` send 10 packets.
There are cases that it is not possible to catch only the interesting
packets using tc rule, so then, it is possible to send many packets and
verify that at least this amount of packets hit the rule.
Add `PING_COUNT` variable, which is set to 10 by default, to allow tests
sending more than 10 packets using the existing ping API.

Add tests similar to vxlan_bridge_1d.sh and vxlan_bridge_1d_port_8472.sh.
The tests set up a topology with three VxLAN endpoints: one
"local", possibly offloaded, and two "remote", formed using veth pairs
and likely purely software bridges. The "local" endpoint is connected to
host systems by a VLAN-unaware bridge.
Since VxLAN tunnels must be unique per namespace, each of the "remote"
endpoints is in its own namespace. H3 forms the bridge between the three
domains.
Send IPv4 packets and IPv6 packets with IPv6 underlay.
Use `TC_FLAG`, which is defined in `forwarding.config` file, for TC
checks. `TC_FLAG` allows testing that on HW datapath, the traffic
actually goes through HW.

The tests are very similar to their VLAN-unaware counterpart
(vxlan_bridge_1d_ipv6.sh and vxlan_bridge_1d_port_8472_ipv6.sh),
but instead of using multiple VLAN-unaware bridges, a single VLAN-aware
bridge is used with multiple VLANs.

Remove `vxlan_ping_test()` which is not used and probably was copied
mistakenly from vxlan_bridge_1d.sh.
This was found while adding an equivalent test for IPv6.

In asymmetric routing the ingress VTEP routes the packet into the
correct VxLAN tunnel, whereas the egress VTEP only bridges the packet to
the correct host. Therefore, packets in different directions use
different VNIs - the target VNI.
Add a test which is similar to the existing IPv4 test to check IPv6.
The test uses a simple topology with two VTEPs and two VNIs and verifies
that ping passes between hosts (local / remote) in the same VLAN (VNI)
and in different VLANs belonging to the same tenant (VRF).
While the test does not check VM mobility, it does configure an anycast
gateway using a macvlan device on both VTEPs.

In a similar fashion to the asymmetric test, add a test for symmetric
routing. In symmetric routing both the ingress and egress VTEPs perform
routing in the overlay network into / from the VxLAN tunnel. Packets in
different directions use the same VNI - the L3 VNI.
Different tenants (VRFs) use different L3 VNIs.
Add a test which is similar to the existing IPv4 test to check IPv6.
