Fixes problems with xtables based MARK target ("ipt" module).
When tc loads the "ipt" (xt) module it kept the symbols local,
this made loading of libxtables not find the required struct.
currently ipt/xt is the only tc action module.
iproute2 never seem to do dlclose.
hopefully the modules doesn't export more symbols then needed.
In this situation hopefully the RTLD_GLOBAL flag won't hurt us.
I've been using this patch in the Debian package of iproute for
the last 3 weeks and noone has complained.

Yep, this is junk. Please give this patch a try:
ss: Avoid quadradic complexity with '-p'
Scan the process list of open sockets once, and store in a hash
table to be used by subsequent find_user() calls.

The tc program searches LIBDIR by default for the .dist files, and that
defaults to /usr/lib. But the netem subdir has /lib/ hardcoded which
means the default build+install results in the files not being found.
Further, these are plain text files which are read at runtime, so it
doesn't make sense to give them executable bits.

Recent gcc doesn't like it when you cast char pointers to uint16_t
pointers and then dereference it. So use memcpy() instead and let
gcc take care of optimizing things away (when appropriate). This
should also fix alignment issues on arches where gcc packs the char
pointer tighter than 16bits.

This patch adds ipv6 filter priority/traffic class function
static int parse_ip6_class(int *argc_p, char ***argv_p, struct tc_u32_sel *sel)
shifting filter value to 5th bit and ignoring "at" as header position
is exactly given.

The recent commit "iproute2: add option to build m_xt as a tc module"
(ab814d6355) looks like it wrongly included debug changes in the
install target. So drop the `echo` so the tc binary actually gets
installed again.

The do_multirule logic was broken in batch mode because
it expected the preferred_family to be AF_INET or AF_INET6,
but it then assigned it to RTNL_FAMILY_IPMR or RTNL_FAMILY_IP6MR.
So, the next iteration of the batch processing, it failed
the check for AF_INET or AF_INET6.

When building on an old environment, the flex generated
tc/emp_ematch.lex.c file would not compile. The error given was:
emp_ematch.lex.c:1686: error: expected â;â, â,â or â)â before numeric constant
The emp_ematch.l uses 'str' as a start symbol name, and flex would create
a '#define str 1' statement. This particular version of flex,
unfortunately, used 'str' as names of string variables in the generated
parser functions. This is line 1686 in the generated file:
YY_BUFFER_STATE ematch__scan_string (yyconst char * str )
This patch just substitutes 'str' for 'lexstr' in emp_ematch.l to avoid
the collision.
This patch fix two issues:
* If kernel is not supporting 6rd then ioctl() call
will return EINVAL, if so just skip perror call.
* 6rd scope is ipv6/ip tunnels. Dont try to fetch
6rd tunnel parms if tunnel protocol != IPPROTO_IPV6.

This will build the xt module (action ipt) of tc as a
shared object that is linked at runtime by tc if used,
rather then built into tc.
This is similar to how the atm qdisc support
is handled (q_atm.so).

making the bus-error reporting configurable and allowing to retrieve
the CAN TX and RX bus error counters via netlink interface. Here is the
