Merge tag 'nf-next-25-11-28' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following batch contains Netfilter updates for net-next:

0) Add sanity check for maximum encapsulations in bridge vlan,
   reported by the new AI robot.

1) Move the flowtable path discovery code to its own file, the
   nft_flow_offload.c mixes the nf_tables evaluation with the path
   discovery logic, just split this in two for clarity.

2) Consolidate flowtable xmit path by using dev_queue_xmit() and the
   real device behind the layer 2 vlan/pppoe device. This allows to
   inline encapsulation. After this update, hw_ifidx can be removed
   since both ifidx and hw_ifidx now point to the same device.

3) Support for IPIP encapsulation in the flowtable, extend selftest
   to cover for this new layer 3 offload, from Lorenzo Bianconi.

4) Push down the skb into the conncount API to fix duplicates in the
   conncount list for packets with non-confirmed conntrack entries,
   this is due to an optimization introduced in d265929930
   ("netfilter: nf_conncount: reduce unnecessary GC").
   From Fernando Fernandez Mancera.

5) In conncount, disable BH when performing garbage collection
   to consolidate existing behaviour in the conncount API, also
   from Fernando.

6) A matching packet with a confirmed conntrack invokes GC if
   conncount reaches the limit in an attempt to release slots.
   This allows the existing extensions to be used for real conntrack
   counting, not just limiting new connections, from Fernando.

7) Support for updating ct count objects in nf_tables, from Fernando.

8) Extend nft_flowtables.sh selftest to send IPv6 TCP traffic,
   from Lorenzo Bianconi.

9) Fixes for UAPI kernel-doc documentation, from Randy Dunlap.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
