gred_change_table_def() takes a pointer to TCA_GRED_DPS attribute,
and expects it will be able to interpret its contents as
struct tc_gred_sopt. Pass the correct gred attribute, instead of
TCA_OPTIONS.
This bug meant the table definition could never be changed after
Qdisc was initialized (unless whatever TCA_OPTIONS contained both
passed netlink validation and was a valid struct tc_gred_sopt...).
Old behaviour:
$ ip link add type dummy
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
RTNETLINK answers: Invalid argument
Now:
$ ip link add type dummy
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0

README
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.
