The firmware / hardware of devices supporting RSS is able to report duplicates and packets that time out inside the reoder buffer. We can now remove all the complex logic that was implemented to keep all the Rx queues more the less synchronized: we used to send a message to all the queues through the firmware to teach the different queues about what is the current SSN every 2048 packets. Now that we rely on the firmware / hardware to detect duplicates, we can completely remove the code that did that in the driver and it has been reported that this code was spuriously dropping legit packets.

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.
