This bug is awaiting verification that the linux- azure-6.8/6.8.0-1017.20~22.04.1 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-6.8' to 'verification-done-jammy-linux-azure-6.8'. If the problem still exists, change the tag 'verification-needed-jammy-linux-azure-6.8' to 'verification-failed-jammy-linux-azure-6.8'.
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.

[Where problems could occur] This is a minor adjustment to the allocated size for MANA RX buffers, fixing the alignment of the resulting SKB in order to improve performance and avoid alignment faults during atomic operations on ARM64. As such, the regression risk seems to be low (especially considering the allocated size for the buffer will end up being bigger, not smaller), but any issues here would impact the reception of network packets in MANA.
