a99ebeeef2 tc: skip actions that don't have options attribute when printing
Modify implementations that return error from action_until->print_aopt()
callback to silently skip actions that don't have their corresponding
TCA_ACT_OPTIONS attribute set (some actions already behave like this).
Print action kind before returning from action_until->print_aopt()
callbacks. This is necessary to support terse dump mode in following patch
in the series.

d5ddb441a5 tc: print all error messages to stderr
Many tc modules were printing error messages to stdout.
This is problematic if using JSON or other output formats.
Change all these places to use fprintf(stderr, ...) instead.

Also, remove unnecessary initialization and places
where else is used after error return.

697dce7b3a net:sched: add action inheritdsfield to skbedit
The new action inheritdsfield copies the field DS of
IPv4 and IPv6 packets into skb->priority. This enables
later classification of packets based on the DS field.

v4:
* Make tc use netlink helper functions

v3:
* Make flag represented in JSON output as a null value

v2:
* Align the output syntax with the input syntax

* Fix the style issues

75ef7b18d2 tc: fix parsing of the control action
If the user didn't specify any control action, don't pop the command line
arguments: otherwise, parsing of the next argument (tipically the 'index'
keyword) results in an error, causing the following 'tc-testing' failures:

 Test a6d6: Add skbedit action with index
 Test 38f3: Delete skbedit action
 Test a568: Add action with ife type
 Test b983: Add action without ife type
 Test 7d50: Add skbmod action to set destination mac
 Test 9b29: Add skbmod action to set source mac
 Test e93a: Delete an skbmod action

Also, add missing parse for 'ok' control action to m_police, to fix the
following 'tc-testing' failure:

 Test 8dd5: Add police action with control ok

tested with:
 # ./tdc.py

test results:
 all tests ok using kernel 4.16-rc2, except 9aa8 "Get a single skbmod
 action from a list" (which is failing also before this commit)

c14f9d92ee treewide: Use addattr_nest()/addattr_nest_end() to handle nested attributes

netlink buffer: use them instead of open coding.

Use addattr_nest_compat()/addattr_nest_compat_end() where appropriate.

3572e01a09 tc: util: Don't call NEXT_ARG_FWD() in __parse_action_control()
Not all callers want parse_action_control*() to advance the
arguments. For instance act_parse_police() does the argument
advancing itself.
