IPsec packet offload
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2178699 Tested: regular IPsec tests + taint tests Depends: !2284 (merged)
Conflicts: the nfp driver doesn't support IPsec offload, skip those bits
This backports the IPsec packet offload feature. It's marked at tech preview, tainting the kernel when IPsec states/policies using the packet offload flags are created.
