Sorry, these types of "sync" bugs are no longer possible for the 18.04.4-targeted HWE kernel for 2 reasons:

1) The 5.3 kernel is no longer in development. It is a released/supported kernel for Ubuntu 19.10. Therefore, all changes need to meet this update policy:
https://wiki.ubuntu.com/KernelTeam/KernelUpdates

All of these patches do not qualify under that policy. If you believe an individual patch (or set of related patches) do meet this policy, please report a separate bug.

2) We have made exceptions in the past for Kunpeng920-specific drivers. However, Kunpeng920 is now shipping and is an Ubuntu-certified SoC. Therefore the regression risk is now too great to consider exceptions.

Since these changes will automatically be included in 18.04.5, I'll target that milestone.

Several patches in the above list did not actually land in 5.4-rc3. I noted these in the description, and I am considering them out of scope for this bug.

The set of patches that made it into a given release is self evident using "git log", so I suggest not providing a patch list at all in sync bugs.

I have checked it. this aboving patchset is included in this 5.4-rc1 branch. I think it have landed in 5.4-rc3

[dann frazier (dannf)]

Those patches are in v5.5-rc1:

$ git log --oneline v5.4..v5.5-rc1 --grep "net: hns3: add support" --grep "net: hns3: support tx-scatter-gather-fraglist feature"
8ae10cfb50897 net: hns3: support tx-scatter-gather-fraglist feature
8e6de441b8e66 net: hns3: add support for configuring VF MAC from the host

22044f95faa05 net: hns3: add support for spoof check setting
6430f744a45ad net: hns3: add support for setting VF link status on the host

As mentioned in Comment #1, we can not do "full backports" for the 18.04.4 kernels. This bug is targeted at 18.04.*5*, which will ship a >= 5.4 HWE kernel. All 5.4 changes will be introduced at that time.
