In the commit 5e46634529 ("net/mlx5e: IPsec: Add IPsec steering in
local NIC RX"), the decrypted packets are handled in RX error flow
table. There is only one rule in the table, which forwards packets to
the default ESP TIR.
This patch updates the design to allow RSS after decryption. For ESP
traffic, SPI and IP addresses are the fields selected for RSS hash,
and it's common that only one SPI is configured in RX direction, so
RSS can't work properly as all the packets are hashed to one key in
this case. To take advantage of RSS and improve performance, the
decrypted packets need to be forwarded back to TTC table, where RSS
can work based on the decrypted packet types.

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.
