net: sched: gred: introduce per-virtual queue attributes
This series updates the GRED Qdisc. The Qdisc matches nfp offload very
well, but before we can offload it there are a number of improvements
to make.
First few patches add extack messages to the Qdisc and pass extack
to netlink validation.
Next a new netlink attribute group is added, to allow GRED to be
extended more easily. Currently GRED passes C structures as attributes,
and even an array of C structs for virtual queue configuration. User
space has hard coded the expected length of that array, so adding new
fields is not possible.
New two-level attribute group is added:
[TCA_GRED_VQ_LIST]
[TCA_GRED_VQ_ENTRY]
[TCA_GRED_VQ_DP]
[TCA_GRED_VQ_FLAGS]
[TCA_GRED_VQ_STAT_*]
[TCA_GRED_VQ_ENTRY]
[TCA_GRED_VQ_DP]
[TCA_GRED_VQ_FLAGS]
[TCA_GRED_VQ_STAT_*]
[TCA_GRED_VQ_ENTRY]
...
Statistics are dump only. Patch 4 switches the byte counts to be 64 bit,
and patch 5 introduces the new stats attributes for dump. Patch 6
switches RED flags to be per-virtual queue, and patch 7 allows them
to be dumped and set at virtual queue granularity.

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.
