Introduce flowtable hw offloading in airoha_eth driver
Introduce netfilter flowtable integration in airoha_eth driver to
offload 5-tuple flower rules learned by the PPE module if the user
accelerates them using a nft configuration similar to the one reported
below:
table inet filter {
flowtable ft {
hook ingress priority filter
devices = { lan1, lan2, lan3, lan4, eth1 }
flags offload;
}
chain forward {
type filter hook forward priority filter; policy accept;
meta l4proto { tcp, udp } flow add @ft
}
}
Packet Processor Engine (PPE) module available on EN7581 SoC populates
the PPE table with 5-tuples flower rules learned from traffic forwarded
between the GDM ports connected to the Packet Switch Engine (PSE) module.
airoha_eth driver configures and collects data from the PPE module via a
Network Processor Unit (NPU) RISC-V module available on the EN7581 SoC.
Move airoha_eth driver in a dedicated folder
(drivers/net/ethernet/airoha).

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.
