Merge branch 'selftests-Add-tests-for-VXLAN-at-an-802-1d-bridge' 

Ido Schimmel says:

====================
selftests: Add tests for VXLAN at an 802.1d bridge

Petr says:

This patchset adds several tests for VXLAN attached to an 802.1d bridge
and fixes a related bug.

First patch #1 fixes a bug in propagating SKB already-forwarded marks
over veth to bridges, where they are irrelevant. This bug causes the
vxlan_bridge_1d test suite from this patchset to fail as the packets
aren't forwarded by br2.

In patches #2 and #3, lib.sh is extended to support network namespaces.
The use of namespaces is necessitated by VXLAN, which allows only one
VXLAN device with a given VNI per namespace. Thus to host full topology
on a single box for selftests, the "remote" endpoints need to be in
namespaces.

In patches #4-#6, lib.sh is extended in other ways to facilitate the
following patches.

In patches #7-#15, first the skeleton, and later the generic tests
themselves are added.

Patch #16 then adds another test that serves as a wrapper around the
previous one, and runs it with a non-default port number.

Patches #17 and #18 add mlxsw-specific tests. About those, Ido writes:

The first test creates various configurations with regards to the VxLAN
and bridge devices and makes sure the driver correctly forbids
unsupported configuration and permits supported ones. It also verifies
that the driver correctly sets the offload indication on FDB entries and
the local route used for VxLAN decapsulation.

The second test verifies that the driver correctly configures the singly
linked list used to flood BUM traffic and that traffic is flooded as
expected.
