[PATCH net-next 0/4] selftests: forwarding: Tweaks and a new test

[Ido Schimmel]

First patch adds a new test for VLAN-unaware bridges.

Next two patches make the tests fail in case they are missing interfaces
or dependencies.

Last patch allows one to create the veth interfaces even without the
optional configuration file.

Ido Schimmel (4):
  selftests: forwarding: Add a test for VLAN-unaware bridge
  selftests: forwarding: Exit with error when missing dependencies
  selftests: forwarding: Exit with error when missing interfaces
  selftests: forwarding: Allow creation of interfaces without a config

[PATCH net-next 1/4] selftests: forwarding: Add a test for VLAN-unaware bridge

[Ido Schimmel]

Similar to the VLAN-aware bridge test, test the VLAN-unaware bridge and
make sure that ping, FDB learning and flooding work as expected.

[PATCH net-next 2/4] selftests: forwarding: Exit with error when missing dependencies

[Ido Schimmel]

We already return an error when some dependencies (e.g., 'jq') are
missing so lets be consistent and do that for all.

[Ido Schimmel]

Returning 0 gives a false sense of success when the required modules did
not even manage to be initialized and register the required net devices.

[PATCH net-next 4/4] selftests: forwarding: Allow creation of interfaces without a config file

[Ido Schimmel]

Some users want to be able to run the tests without a configuration file
which is useful when one needs to test both virtual and physical
interfaces on the same machine.

Move the defines that set the type of interface to create and whether to
create it away from the optional configuration file to the library like
the rest of the defines.
