There are a lot of things missing in your changelog.

For example: Why do we need a new action here? Why segmentation
is not done on the target device?

At least for the egress side, dev_queue_xmit() is called by act_mirred,
it will perform a segmentation with skb_gso_segment() if needed.
So why bigger packets can not be segmented here?

Please add all these necessary details into your changelog.
