Current hardware doesn't support double encapsulation which is happening when IPsec packet offload tunnel mode is configured together with eswitch encap option. Any user attempt to add new SA/policy after he/she sets encap mode, will generate the following FW syndrome: mlx5_core 0000:08:00.0: mlx5_cmd_out_err:803:(pid 1904): CREATE_FLOW_TABLE(0x930) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xa43321), err(-22) Make sure that we block encap changes before creating flow steering tables. This is applicable only for packet offload in tunnel mode, while packet offload in transport mode and crypto offload, don't have such limitation as they don't perform encapsulation.

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 Restructured Text 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.
