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"
(ab814d63) looks like it wrongly included debug changes in the
install target.  So drop the `echo` so the tc binary actually gets

Get ip rule parsing of "dsfield" in sync with ip route parsing and manual page.
Signed-off-by: Arnd Hannemann <hannemann@nets.rwth-aachen.de>

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.

`ip -s link` shows interface counters truncated to 32 bit. This is
because interface statistics are transported only in 32-bit quantity
to userspace. This commit adds recognition for the new IFLA_STATS64
attribute that exports them in full 64 bit.

The kernel interface changed just before 2.6.34 was released.  This brings
iproute2 in line with the current changes.  The VF portion of setlink is
comprised of a set of nested attributes.

  IFLA_VFINFO_LIST (NESTED)

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 ‘;’, ‘,’ or ‘)’ 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.

2.6 kernel allows 2^32 route tables, but documentation stated only
255 values were possible.

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.

Other commands are quiet if successful. mirred action had leftover

XT_ALIGN() calls ALIGN macro but ALIGN is in kernel source not userspace.

Try to automatically detect iptables modules directory.

Make the configure script look for iptables modules.
This also makes it possible to specify it on the
command line while building via "make IPT_LIB_DIR=/foo/bar".

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