Modify the packet pacing algorithm so that it works with multi-buffer packets. This algorithm makes sure we do not send too many buffers to the receiving thread so that packets have to be dropped. The previous algorithm made the assumption that each packet only consumes one buffer, but that is not true anymore when multi-buffer support gets added. Instead, we find out what the largest packet size is in the packet stream and assume that each packet will consume this many buffers. This is conservative and overly cautious as there might be smaller packets in the stream that need fewer buffers per packet. But it keeps the algorithm simple. Also simplify it by removing the pthread conditional and just test if there is enough space in the Rx thread before trying to send one more batch. Also makes the tests run faster.

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.
