Rather than tracking the number of receive buffer transactions that have been submitted without a doorbell, just track the total number of transactions that have been issued. Then ring the doorbell when that number modulo the replenish batch size is 0. The effect is roughly the same, but the new count is slightly more interesting, and this approach will someday allow the replenish batch size to be tuned at runtime.

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.
