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)

Fixes: 3572e01a09 ("tc: util: Don't call NEXT_ARG_FWD() in __parse_action_control()")

d17b136f7d Use C99 style initializers everywhere
This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).

Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.

The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.

4bfb21ca20 policer - retire old syntax

commit b82057d9ec851a8aba8a295b959190ef5098f330
Author: Jamal Hadi Salim <jhs@mojatatu.com>
Date:   Sat Dec 21 17:00:11 2013 -0500

    After a decade of trying to deprecate the old policer syntax,
    I believe it is time to kill it. The kernel build option for old
    policer is gone for at least 5 years now (although backward
    compatibility is still there). Being backward compatible meant
    hijacking the keyword "action" and was obstructing policies like:

    tc filter add dev eth0 parent ffff: protocol ip pref 10 \
    u32 match ip protocol 1 0xff flowid 1:10 \
    action skbedit mark 1 \
    action police rate 10kbit burst 10k pipe \
    action skbedit mark 2 \
    action police rate 20kbit burst 20k pipe \
    action action mirred egress mirror dev dummy0

3e92ff522a linklayer interface between kernel and tc/userspace
This iproute2 tc patch is connected to the kernel
 - commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling)

The rate table calculated by tc, have gotten replaced in the kernel
and is no-longer used for lookups.

This happened in kernel release v3.8 caused by kernel
 - commit 56b765b79 ("htb: improved accuracy at high rates").
This change unfortunately caused breakage of tc overhead and
linklayer parameters.

 Kernel overhead handling got fixed in kernel v3.10 by
 - commit 01cb71d2d47 (net_sched: restore "overhead xxx" handling)

 Kernel linklayer handling got fixed in kernel v3.11 by
 - commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling)

The linklayer fix introduced a struct change, that allow the linklayer
attribute to be transferred between tc and kernel. This patch make use
of this linklayer attribute.

The linklayer setting is transfer to the kernel.  And linklayer
setting received from the kernel is printed with a prefixed
"linklayer" when listing current configuration.  The default
TC_LINKLAYER_ETHERNET is only printed in detailed output mode.

ef1d6f97ec Revert "TC action parsing bug fix"
This reverts commit 720a2e8d99.

After further investigation it seems clear to me that reverting the
commit 720a2e8d990707749b2... is the correct thing to do, since the real
fix for the problem this commit was supposed to fix was instead fixed in
commit c29391c7c68f031e246c...

Whatever you specify after a u32 police you will now get a syntax error,
and according to "tc filter add u32 help" there are several things that
you are supposed to be able to specify after a police.

So, Steven, please revert 720a2e8d990707749b2...

because -1 indicate that the cell_log needs to be computed by the

OK this patch fixes parsing of "action ...". I've removed
the erroring on unknown arguments again since in that case
the caller should continue parsing.

Good catch. It seems this is merely a parsing error, iproute doesn't
have an "action" parameter and aborts parsing, so it uses the default
value of "RECLASSIFY". It never had this parameter, so this patch
removes it from the help text and makes it return an error.

by tc_calc_xmitsize() calls.
