For better error reporting to user space, add extack messages when
skbedit action offload fails.
Example:
# echo 1 > /sys/kernel/tracing/events/netlink/netlink_extack/enable
# tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action skbedit queue_mapping 1234
Error: cls_matchall: Failed to setup flow action.
We have an error talking to the kernel
# cat /sys/kernel/tracing/trace_pipe
tc-185 [002] b..1. 31.802414: netlink_extack: msg=act_skbedit: Offload not supported when "queue_mapping" option is used
tc-185 [002] ..... 31.802418: netlink_extack: msg=cls_matchall: Failed to setup flow action
# tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action skbedit inheritdsfield
Error: cls_matchall: Failed to setup flow action.
We have an error talking to the kernel
# cat /sys/kernel/tracing/trace_pipe

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.
