[SRU][J:linux-bluefield][PATCH v1 00/32] support IPsec full offload

[Tony Duan]

BugLink: https://bugs.launchpad.net/bugs/2034578

Align Kernel IPsec Full offload implementation in the DPU to the upstream Full
offload in all components: OFED, Strongswan, etc. This commit is in order for
DPU Kernel IPsec to include policy offload and be fully aligned to what
ConnectX Kernel customers will use.

Most of the changes are already in uptream. In this commit, it contains 32
patches include 4 reverts, 27 cherry-picks and 1 conflict resolver.
Most of the patches are clean cherry-pick. The conflict are mainly
focus on driver part and netdev_***() related functions. I ignored
driver change and keep dev_***() unchanged.

This commit also depends on
"[SRU][J:linux-bluefield][PATCH v1 0/1] UBUNTU: [Config] bluefield: disable MLX5, and vendor drivers."
(https://lists.ubuntu.com/archives/kernel-team/2023-September/142502.html)
which is still under review.
