Add cases to check minimum and maximum MTU which are exposed via "ip -d link show". Test configuration and traffic.

2024-03-28selftests: forwarding: Add a test for testing lib.sh functionalityPetr Machata1-0/+1
Rerunning various scenarios to make sure lib.sh changes do not impact the observable behavior is no fun. Add a selftest at least for the bare basics -- the mechanics of setting RET, retmsg, and EXIT_STATUS. Since the selftest itself uses lib.sh, it would be possible to break lib.sh in such a way that invalidates result of the selftest. Since the metatest only uses the bare basics (just pass/fail), hopefully such fundamental breakages would be noticed.

2024-03-28selftests: forwarding: Move several selftestsPetr Machata1-8/+0
The tests in net/forwarding are generally expected to be HW-independent. There are however several tests that, while not depending on any HW in particular, nevertheless depend on being used on HW interfaces. Placing these selftests to net/forwarding is confusing, because the selftest will just report it can't be run on veth pairs. At the same time, placing them to a particular driver's selftests subdirectory would be wrong. Instead, add a new directory, drivers/net/hw, where these generic but HW independent selftests should be placed. Move over several such tests including one helper library. Since typically these tests will not be expected to run, omit the directory drivers/net/hw from the TARGETS list in selftests/Makefile. Retain a Makefile in the new directory itself, so that a user can make -C into that directory and act on those tests explicitly.

2024-01-31selftests: forwarding: Remove duplicated lib.sh contentPetr Machata1-0/+3
commit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh to contain code shared by tests under net/ and net/forwarding/. However, this caused issues with selftests from directories other than net/forwarding/, in particular those under drivers/net/. Those issues were avoided in a simple way by duplicating some content in commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to remove the duplicated content, restore the inclusion of net/lib.sh from net/forwarding/lib.sh but with the following changes: * net/lib.sh is imported through the net_forwarding_dir path The original expression "source ../lib.sh" would look for lib.sh in the directory above the script file's one, which did not work for tests under drivers/net/. * net/lib.sh is added to TEST_INCLUDES Since net/forwarding/lib.sh now sources net/lib.sh, both of those files must be exported along with tests which source net/forwarding/lib.sh.

2023-04-20selftests: forwarding: add a test for MAC Merge layerVladimir Oltean1-0/+1
The MAC Merge layer (IEEE 802.3-2018 clause 99) does all the heavy lifting for Frame Preemption (IEEE 802.1Q-2018 clause 6.7.2), a TSN feature for minimizing latency. Preemptible traffic is different on the wire from normal traffic in incompatible ways. If we send a preemptible packet and the link partner doesn't support preemption, it will drop it as an error frame and we will never know. The MAC Merge layer has a control plane of its own, which can be manipulated (using ethtool) in order to negotiate this capability with the link partner (through LLDP). Actually the TLV format for LLDP solves this problem only partly, because both partners only advertise: - if they support preemption (RX and TX) - if they have enabled preemption (TX) so we cannot tell the link partner what to do - we cannot force it to enable reception of our preemptible packets. That is fully solved by the verification feature, where the local device generates some small probe frames which look like preemptible frames with no useful content, and the link partner is obliged to respond to them if it supports the standard. If the verification times out, we know that preemption isn't active in our TX direction on the link. Having clarified the definition, this selftest exercises the manual (ethtool) configuration path of 2 link partners (with and without verification), and the LLDP code path, using the openlldp project. The test also verifies the TX activity of the MAC Merge layer by sending traffic through a traffic class configured as preemptible (using mqprio). There isn't a good way to make this really portable (user space cannot find out how many traffic classes there are for a device), but I chose num_tc 4 here, that should work reasonably well. I also know that some devices (stmmac) only permit TXQ0 to be preemptible, so this is why PREEMPTIBLE_PRIO was strategically chosen as 0. Even if other hardware is more configurable, this test should cover the baseline. This is not really a "forwarding" selftest, but I put it near the other "ethtool" selftests. $ ./ethtool_mm.sh eno0 swp0 TEST: Manual configuration with verification: eno0 to swp0 [ OK ] TEST: Manual configuration with verification: swp0 to eno0 [ OK ] TEST: Manual configuration without verification: eno0 to swp0 [ OK ] TEST: Manual configuration without verification: swp0 to eno0 [ OK ] TEST: Manual configuration with failed verification: eno0 to swp0 [ OK ] TEST: Manual configuration with failed verification: swp0 to eno0 [ OK ] TEST: LLDP [ OK ] Signed-off-by: Vladimir Oltean <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
