Bug Description

The cloud vendor is requesting backport of 13 patches from upstream. These changes are mostly improvements to the bpf networking-related code.

Please see the SalesForce case for more information:

https://canonical.lightning.force.com/lightning/r/Case/5003z000027kZitAAE/view

[Impact]
Without these patches, BPF functionality is incomplete in current 5.4 kernels

[Fix]
Add missing (networking) BPF code from upstream.

[Test]
The cloud vendor has tested these patches, before submitting them upsteam and then backporting for the Ubuntu 5.4 kernel

[Regression Potential]
Low. These changes are mostly extending BPF functionality in the net code not changing existing code.
