Introduce decrypt FT, the RX error FT, and the default rules. The PSP (PSP) RX decrypt flow table is pointed by the TTC (Traffic Type Classifier) UDP steering rules. The decrypt flow table has two flow groups. The first flow group keeps the decrypt steering rule programmed always when PSP packet is recognized using the dedicated udp destination port number 1000, if packet is decrypted then a PSP marker is set in metadata_regB[30]. The second flow group has a default rule to forward all non-offloaded PSP packet to the TTC UDP default RSS TIR. The RX error flow table is the destination of the decrypt steering rules in the PSP RX decrypt flow table. It has two fixed rule one with single copy action that copies psp_syndrome to metadata_regB[23:29]. The PSP marker and syndrome is used to filter out non-psp packet and to return the PSP crypto offload status in Rx flow. The marker is used to identify such packet in driver so the driver could set SKB PSP metadata. The destination of RX error flow table is the TTC UDP default RSS TIR. The second rule will drop packets that failed to be decrypted (like in case illegal SPI or expired SPI is used).

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.
