Hi Viktor, As your proposal of setting autoprobe=0 before updating sriov_numvfs is the vendor-recommended sequence, it makes sense to implement it.
Are you planning to submit a PR? If so, I'm happy to review. Otherwise, I can add it to my task-list and prioritize it accordingly. ------------------------------------------------------- For reference, I could not reproduce the issue on the following setup: I tried to reproduce this on romano-machine: - Ubuntu 22.04 (jammy) and 24.04 (noble) - Kernel 6.8.0-138-generic (HWE) (jammy) - In-tree mlx5_core - ConnectX-6 Dx (Lenovo OEM, PSID LNV0000000029, 15b3:101d) - Firmware 22.36.1010 - With virtual-function-count values up to 32 (sriov_numvfs=32) Notable difference is the firmware version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2166228 Title: Mellanox NIC is unable to enter switchdev mode To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/2166228/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
