Carolina Jubran 7593439c13 net/mlx5: Prevent tunnel mode conflicts between FDB and NIC IPsec tables
When creating IPsec flow tables with tunnel mode enabled, the driver
uses mlx5_eswitch_block_encap() to prevent tunnel encapsulation
conflicts across different domains (NIC_RX/NIC_TX and FDB), since the
firmware doesn’t allow both at the same time.

Currently, the driver attempts to reserve tunnel mode unconditionally
for both NIC and FDB IPsec tables. This can lead to conflicting tunnel
mode setups, for example, if a flow table was created in the FDB
domain with tunnel offload enabled, and we later try to create another
one in the NIC, or vice versa.

To resolve this, adjust the blocking logic so that tunnel mode is only
reserved by NIC flows. This ensures that tunnel offload is exclusively
used in either the NIC or the FDB, and avoids unintended offload
conflicts.

Fixes: 1762f132d5 ("net/mlx5e: Support IPsec packet offload for RX in switchdev mode")
Fixes: c6c2bf5db4 ("net/mlx5e: Support IPsec packet offload for TX in switchdev mode")

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.
