If a packet modification is done before a missable action such as CT and there is a miss in CT after it, this may cause a miss match when resuming re-executing the same chain in software, and wrong packet count. This use case for example is a stateless (static) nat. * brief explanation of fixes Add support for missing to a specific action instance, and support of per action hardware stats to update what was actually done in hardware. BugLink: <a href="https://bugs.launchpad.net/bugs/2012571">https://bugs.launchpad.net/bugs/2012571</a> Note: We previously sent this patch to Focal but revert the series due to some issue. For Jammy, there is no such issue so we'd like to merge this series to Jammy, while in the meantime working on solving the Focal issue, thanks. And because this has been review for Focal, and no code change, I propagate the acks/review tags.
