linux-toradex.git/include/uapi/linux/tc_act/tc_skbedit.h, branch v5.17 Linux kernel for Apalis and Colibri modules net: Move all TC actions identifiers to one place 2019-02-10T17:28:43+00:00 Eli Cohen eli@mellanox.com 2019-02-10T12:24:59+00:00 257eeded20b34219d5484cfc415b3e39093f37b8 Move all the TC identifiers to one place, to the same enum that defines the identifier of police action. This makes it easier choose numbers for new actions since they are now defined in one place. We preserve the original values for binary compatibility. New IDs should be added inside the enum.

v4:
*Not allow setting flags other than the expected ones.

*Allow dumping the pure flags.

v3:
*Use optional flags, so that it won't break old versions of tc.

*Allow users to set both SKBEDIT_F_PRIORITY and SKBEDIT_F_INHERITDSFIELD flags.

v2:
*Fix the style issue

*Move the code from skbmod to skbedit

License cleanup: add SPDX license identifier to uapi header files with a license 2017-11-02T10:20:11+00:00 Greg Kroah-Hartman gregkh@linuxfoundation.org 2017-11-01T14:09:13+00:00 e2be04c7f9958dde770eeb8b30e829ca969b37bb Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

Extremely useful for setting packet type to host so i dont
have to modify the dst mac address using pedit (which requires
that i know the mac address)

Example usage:
tc filter add dev eth0 parent ffff: protocol ip pref 9 u32 \
match ip src 5.5.5.5/32 \
flowid 1:5 action skbedit ptype host

This will tag all packets incoming from 5.5.5.5 with type
PACKET_HOST
