This bug is awaiting verification that the linux- bluefield/5.15.0-1014.16 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification- done-jammy'. If the problem still exists, change the tag 'verification- needed-jammy' to 'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Nothing is being transmitted, and nothing is received. The RX error count keeps on increasing (check ifconfig oob_net0). After several minutes, the RX error count stagnates and the oob finally gets an ip and is pingable. [Fix] The issue is in the mlxbf_gige_rx_init function. As soon as the RX DMA is enabled, the RX CI reaches the max 128, it becomes equal to RX PI. And RX CI doesn't decrease since the code hasn't ran phy_start yet. The solution is to move the rx init after phy_start. This fix applies to both 5.4 and 5.15. [Test Case] * Check if the gige driver is loaded * Check that the oob_net0 interface is up and pingable from an external host * Do at ~1000 resets and powercycles and check the oon_net0 interface again [Regression Potential] * No known regressions.
