When a frame is injected from CPU, it is required to create an IFH(Inter frame header) which sits in front of the frame that is transmitted. This IFH, contains different fields like destination port, to bypass the analyzer, priotity, etc. Lan966x it is using packing library to set and get the fields of this IFH. But this seems to be an expensive operations. If this is changed with a simpler implementation, the RX will be improved with ~5Mbit while on the TX is a much bigger improvement as it is required to set more fields. Below are the numbers for TX.

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.
