====================
pull request (net): ipsec 2024-07-11
1) Fix esp_output_tail_tcp() on unsupported ESPINTCP.
From Hagar Hemdan.
2) Fix two bugs in the recently introduced SA direction separation.
From Antony Antony.
3) Fix unregister netdevice hang on hardware offload. We had to add another
list where skbs linked to that are unlinked from the lists (deleted)
but not yet freed.
4) Fix netdev reference count imbalance in xfrm_state_find.
From Jianbo Liu.
5) Call xfrm_dev_policy_delete when killingi them on offloaded policies.
Jianbo Liu.
