This bug is awaiting verification that the linux-
azure-6.11/6.11.0-1012.12~24.04.1 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-noble-linux-
azure-6.11' to 'verification-done-noble-linux-azure-6.11'. If the
problem still exists, change the tag 'verification-needed-noble-linux-
azure-6.11' to 'verification-failed-noble-linux-azure-6.11'.


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. Thank you!

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=58a63729c957

  1705341485ff ("net: mana: Improve mana_set_channels() in low mem conditions")
  
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=1705341485ff

  [Fix]

  58a63729c957 ("net: mana: Fix doorbell out of order violation and avoid 
unnecessary doorbell rings")
  - jammy, oracular: already in the tree
  - noble: cherry-pick

  3410d0e14f9a ("net: mana: Implement get_ringparam/set_ringparam for mana")
  - oracular, noble: cherry-pick
  - jammy: backported

  1705341485ff ("net: mana: Improve mana_set_channels() in low mem conditions")
  - oracular, noble: cherry-pick
  - jammy: backported

  [Test plan]

  Compile tested only.

  [Where problems could occur]

  The fixes are relatively small and self-contained, so the regression
  risk seems low; however, issues with them would cause degraded network
  operation on machines using the MANA ethernet drivers.
