2025-02-27selftests: drv-net: Check if combined-count existsJoe Damato
Some drivers, like tg3, do not set combined-count: $ ethtool -l enp4s0f1 Channel parameters for enp4s0f1: Pre-set maximums: RX: 4 TX: 4 Other: n/a Combined: n/a Current hardware settings: RX: 4 TX: 1 Other: n/a Combined: n/a In the case where combined-count is not set, the ethtool netlink code in the kernel elides the value and the code in the test: netnl.channels_get(...) With a tg3 device, the returned dictionary looks like: {'header': {'dev-index': 3, 'dev-name': 'enp4s0f1'}, 'rx-max': 4, 'rx-count': 4, 'tx-max': 4, 'tx-count': 1} Note that the key 'combined-count' is missing. As a result of this missing key the test raises an exception: # Exception| if channels['combined-count'] == 0: # Exception| ~~~~~~~~^^^^^^^^^^^^^^^^^^ # Exception| KeyError: 'combined-count' Change the test to check if 'combined-count' is a key in the dictionary first and if not assume that this means the driver has separate RX and TX queues. With this change, the test now passes successfully on tg3 and mlx5 (which does have a 'combined-count').

Move the KEY_PATH variable definition inside the set_user_data function to reduce global variables and improve encapsulation. The KEY_PATH variable is now dynamically created when setting user data.

2024-12-16selftests: net-drv: queues: sanity check netlink dumpsJakub Kicinski
This test already catches a netlink bug fixed by this series, but only when running on HW with many queues. Make sure the netdevsim instance created has a lot of queues, and constrain the size of the recv_buffer used by netlink. While at it test both rx and tx queues.

2024-12-06selftests: mlxsw: sharedbuffer: Ensure no extra packets are countedDanielle Ratson
The test assumes that the packet it is sending is the only packet being passed to the device. However, it is not the case and so other packets are filling the buffers as well. Therefore, the test sometimes fails because it is reading a maximum occupancy that is larger than expected. Add egress filters on $h1 and $h2 that will guarantee the above.

On both port_tc_ip_test() and port_tc_arp_test(), the max occupancy is checked on $h2 twice, when only the error message is different and does not match the check itself.

2024-12-06selftests: mlxsw: sharedbuffer: Remove h1 ingress test caseDanielle Ratson
The test is sending only one packet generated with mausezahn from $h1 to $h2. However, for some reason, it is testing for non-zero maximum occupancy in both the ingress pool of $h1 and $h2. The former only passes when $h2 happens to send a packet. Avoid intermittent failures by removing unintentional test case regarding the ingress pool of $h1.

Extend the rss_ctx test suite to test that an ntuple action that redirects to an RSS context contains that information in `ethtool -n`. Otherwise the output from ethtool is highly deceiving. This test helps ensure drivers are compliant with the API.

The combination of ntuple action (ring_cookie) and RSS context can cause an ntuple rule to target a higher queue than appears in any RSS indirection table or directly in the ntuple rule, since the two numbers are added together.
