Subject: [PATCH net-next v25 00/23] Introducing OpenVPN Data Channel
Offload
Notable changes since v24:
* disable TCP disconnections of attached sockets (tcp_disconnect()
returns -EBUSY) - similarly to kTLS.
* used rcu_replace_pointer instead of rcu_dereference_protected+rcu_assign_pointer
* dropped useless skb->ignore_df = 1
* dropped unneded EXPORT_SYMBOL_GPL(udpv6_prot)
* dropped obsolete comment for ovpn_crypto_key_slots_swap()
* dropped calls to kfree() in ovpn_aead_encrypt/decrypt() (release is
performed in ovpn_encrypt/decrypt_post())
* dropped NULL check before calling kfree() in
ovpn_encrypt/decrypt_done()
* converted seq_num from atomic64_t to atomic_t (IV exhaustion is now
detected in case of wrap around)
* call consume_skb() on skb when dropping keepalive message (it is not a
failure)
* made REMOTE_PORT mandatory when REMOTE_IPV4/6 is specified in
peer_new/set call
* ensured ovpn_nl_key_swap_notify() is called only once, even when
parsing a batch of received packets concurrently
Please note that some patches were already reviewed/tested by a few
people. These patches have retained the tags as they have hardly been
touched.

Thanks a lot!
