Linux kernel source tree

Rx flow steering consists of two flow tables (FTs). The first FT (crypto table) have one default miss rule so non MACsec offloaded packets bypass the MACSec tables. All others flow table entries (FTEs) are divided to two equal groups size, both of them are for MACsec packets: The first group is for MACsec packets which contains SCI field in the SecTAG header. The second group is for MACsec packets which doesn't contain SCI, where need to match on the source MAC address (only if the SCI is built from default MACsec port). Destination MAC address, ethertype and some of SecTAG fields are also matched for both groups. In case of match, invoke decrypt action on the packet. For each MACsec Rx offloaded SA two rules are created: one with SCI and one without SCI. The second FT (check table) has two fixed rules: One rule is for verifying that the previous offload actions were finished successfully. In this case, need to decap the SecTAG header and forward the packet for further processing. Another default rule for dropping packets that failed in the previous decrypt actions. The MACsec FTs are created on demand when the first MACsec rule is added and destroyed when the last MACsec rule is deleted.

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.
