selftests: drv-net: fix RPS mask handling in toeplitz test

2026-01-14T03:13:08Z

The toeplitz.py test passed the hex mask without "0x" prefix (e.g., "300" for CPUs 8,9). The toeplitz.c strtoul() call wrongly parsed this as decimal 300 (0x12c) instead of hex 0x300. Pass the prefixed mask to toeplitz.c, and the unprefixed one to sysfs.

selftests: hw-net: toeplitz: give the test up to 4 seconds

2025-11-25T02:51:41Z

Increase the receiver timeout. When running between machines in different geographic regions the test needs more than a second to SSH across and send the frames. The bkg() command that runs the receiver defaults to 5 sec timeout, so using 4 sec sounds like a reasonable value for the receiver itself.

selftests: hw-net: toeplitz: read the RSS key directly from C

2025-11-25T02:51:40Z

Now that we have YNL support for RSS accessing the RSS info from C is very easy. Instead of passing the RSS key from Python do it directly in the C code. Reviewed-by: Willem de Bruijn Link: https://patch.msgid.link/20251121040259.3647749-4-kuba@kernel.org Signed-off-by: Jakub Kicinski

selftests: hw-net: toeplitz: make sure NICs have pure Toeplitz configured

2025-11-25T02:51:40Z

Make sure that the NIC under test is configured for pure Toeplitz hashing, and no input key transform (no symmetric hashing). Reviewed-by: Willem de Bruijn Link: https://patch.msgid.link/20251121040259.3647749-3-kuba@kernel.org Signed-off-by: Jakub Kicinski

selftests: drv-net: hw: convert the Toeplitz test to Python

2025-11-21T02:19:30Z

Rewrite the existing toeplitz.sh test in Python. The conversion is a lot less exact than the GRO one. We use Netlink APIs to get the device RSS and IRQ information. We expect that the device has neither RPS nor RFS configured, and set RPS up as part of the test.
