It's time to differentiate between Rx and Tx ring sizes. Not only Tx rings are processed differently than Rx rings, but their default number also differs - i.e. up to 8 Tx rings per device (8 traffic classes) vs. 2 Rx rings (one per CPU). So let's set Tx rings sizes to half the size of the Rx rings for now, to be conservative. The default ring sizes were decreased as well (to the next lower power of 2), to reduce the memory footprint, buffering etc., since the measurements I've made so far show that the rings are very unlikely to get full. This change also anticipates the introduction of the dynamic interrupt moderation (dim) algorithm which operates on maximum packet thresholds of 256 packets for Rx and 128 packets for Tx.

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.
