When we iterate through the BDs in the RX ring, the software producer index (which is already passed by value to enetc_rxbd_next) lags behind, and we end up with this funny looking "++i == rx_ring->bd_count" check so that we drag it after us. Let's pass the software producer index "i" by reference, so that enetc_rxbd_next can increment it by itself (mod rx_ring->bd_count), especially since enetc_rxbd_next has to increment the index anyway.

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.
