Currently, the driver will schedule RX ring reset when we get a buffer error in the RX completion record. These RX buffer errors can be due to normal out-of-buffer conditions or a permanent error in the RX ring. Because the driver cannot distinguish between these 2 conditions, we assume all these buffer errors require reset. This is very disruptive when it is just a normal out-of-buffer condition. Newer firmware will now monitor the rings for the permanent failure and will send a notification to the driver when it happens. This allows the driver to reset only when such a notification is received. In environments where we have predominently out-of-buffer conditions, we now can avoid these unnecessary resets.

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.
