tools/selftests: Add a VXLAN+IPsec traffic test

2026-04-28T04:47:19+00:00

There are VXLAN tests and IPsec tests, but there is no test that
combines the two protocols and exercises the tunnel-over-ipsec code
paths. Fix that by adding a traffic test with VXLAN and IPsec using
crypto offload. This is runnable on HW which supports ESP offload (so no
nsim unfortunately).

Traffic is done with iperf3 and the test validates that there are no
packet drops and iperf3 can get to at least 100 Mbps (a very
conservative value on today's crypto offload HW, as it can typically
reach multi-Gbps rates).

Ran right now, the test fails due to a recently exposed bug in xfrm,
which will be fixed in the next patch:

selftests/net: Split netdevsim tests from HW tests in nk_qlease

2026-04-14T15:17:01+00:00

As pointed out in 3d2c3d2eea9a ("selftests: net: py: explicitly forbid
multiple ksft_run() calls"), ksft_run() cannot be called multiple times.

Move the netdevsim-based queue lease tests to selftests/net/ so that
each file has exactly one ksft_run() call.

The HW tests (io_uring ZC RX, queue attrs, XDP with MP, destroy) remain
in selftests/drivers/net/hw/.

selftests: drv-net: ntuple: Add dst-ip, src-port, dst-port fields

2026-04-10T22:32:11+00:00

Extend the ntuple flow steering test to cover dst-ip, src-port, and
dst-port fields. The test supports arbitrary combinations of the fields,
for now we test src_ip/dst_ip, and src_ip/dst_ip/src_port/dst_port.

The tests currently match full fields, but we can consider adding
support for masked fields in the future.

selftests: drv-net: Add ntuple (NFC) flow steering test

2026-04-10T22:32:11+00:00

Add a test for ethtool NFC (ntuple) flow steering rules. The test
creates an ntuple rule matching on various flow fields and verifies
that traffic is steered to the correct queue.

The test forces all traffic to queue 0 via the indirection table,
then installs an ntuple rule to steer select traffic to a specific
queue. The test then verifies the expected number of packets is received
on the queue.

This test has variants for TCP/UDP over IPv4/IPv6, with rules matching
the source IP. Additional match fields will be added in the next commit.

selftests/net: Add queue leasing tests with netkit

2026-04-10T01:21:47+00:00

Add extensive selftests for netkit queue leasing, using io_uring zero
copy test binary inside of a netns with netkit. This checks that memory
providers can be bound against virtual queues in a netkit within a
netns that are leasing from a physical netdev in the default netns.
Also add various test cases around corner cases for the queue creation
itself as well as queue info dumping and teardown in case of netkit in
device pair and single mode.

selftests: drivers: hw: add test for the ethtool standard counters

2026-04-02T10:11:04+00:00

Add a new selftest - ethtool_std_stats.sh - which validates the
eth-ctrl, eth-mac and pause standard statistics exported by an
interface. Collision related eth-mac counters as well as the error ones
will be checked against zero since that is the most likely correct
scenario.

The central part of this patch is the traffic_test() function which
gathers the 'before' counter values, sends a batch of traffic and then
interrogates again the same counters in order to determine if the delta
is on target. The function receives an array through which the caller
can request what counters to be interrogated and, for each of them, what
is their target delta value.

The output from this selftest looks as follows on a LX2160ARDB board:

Please note that not all MACs are counting the software injected pause
frames as real Tx pause. For example, on a LS1028ARDB the selftest
output will reflect the fact that neither the ENETC MAC, nor the Felix
switch MAC are able to detect Tx pause frames injected by software.

 $ ./run_kselftest.sh -t drivers/net/hw:ethtool_std_stats.sh

selftests: drivers: hw: update ethtool_rmon to work with a single local interface

2026-04-02T10:11:04+00:00

This patch finalizes the transition to work with a single local
interface for the ethtool_rmon.sh test. Each 'ip link' and 'ethtool'
command used by the test is annotated with the necessary run_on in
order to be executed on the necessary target system, be it local, in
another network namespace or through ssh.

Since we need NETIF up and running also for control traffic, we now
expect that the interfaces are up and running and do not touch bring
them up or down at the end of the test. This is also documented in the
drivers/net/README.rst.

The ethtool_rmon.sh script can still be used in the older fashion by
passing two interfaces as command line arguments, the only restriction
is that those interfaces need to be already up.

 $ DRIVER_TEST_CONFORMANT=no ./ethtool_rmon.sh eth0 eth1

As part of the kselftest infrastructure, this test can be run in the
following manner:

 $ make -C tools/testing/selftests/ TARGETS="drivers/net drivers/net/hw" \
 install INSTALL_PATH=/tmp/ksft-net-drv
 $ cd /tmp/ksft-net-drv/
 $ cat > ./drivers/net/net.config <
