Jakub Kicinski says: ==================== gred: add offload support This series adds support for GRED offload in the nfp driver. So far we have only supported the RED Qdisc offload, but we need a way to differentiate traffic types e.g. based on DSCP marking. It may seem like PRIO+RED is a good match for this job, however, (a) we don't need strict priority behaviour of PRIO, and (b) PRIO uses the legacy way of mapping ToS fields to bands, which is quite awkward and limitting. The less commonly used GRED Qdisc is a better much for the scenario, it allows multiple sets of RED parameters and queue lengths to be maintained with a single FIFO queue. This is exactly how nfp offload behaves. We use a trivial u32 classifier to assign packets to virtual queues. There is also the minor advantage that GRED can't have its child changed, therefore limitting ways in which the configuration of SW path can diverge from HW offload. Last patch of the series adds support for (G)RED in non-ECN mode, where packets are dropped instead of marked. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
