This bug is awaiting verification that the linux-azure/5.15.0-1055.63 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-linux-azure' to 'verification-done-jammy- linux-azure'. If the problem still exists, change the tag 'verification- needed-jammy-linux-azure' to 'verification-failed-jammy-linux-azure'.
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.

After I pick up the upstream patch(es) to enable PCI relaxed ordering (RO) for the Mellanox VF NIC, the throughput goes up to 30.4 Gbps.
