Linux kernel source tree

The statistics of the ring are all unsigned int type, so the statistics will overflow quickly under heavy traffic. In addition, the statistics of struct net_device_stats are obtained from struct enetc_ring_stats, but the statistics of net_device_stats are unsigned long type. So it is better to keep the statistics types consistent in these two structures. Considering these two factors, and the fact that both LS1028A and i.MX95 are arm64 architecture, the statistics of enetc_ring_stats are changed to unsigned long type. Note that unsigned int and unsigned long are the same thing on some systems, and on such systems there is no overflow advantage of one over the other.

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.
