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)
    IFLA_VF_INFO (NESTED)
      IFLA_VF_MAC
      IFLA_VF_VLAN
      IFLA_VF_TX_RATE

Add some missing pieces. Still need to add doucmentation for rest
of vlan arguments.

Last minute IOV format change.

ip addrlabel outputs if%d names due to missing init call:
$ ip addrlabel s
prefix a::42/128 dev if4 label 1000

Also, ip did not accept "if%d" interfaces on input.

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.

This is similar to how the atm qdisc support
is handled (q_atm.so).

Other commands are quiet if successful. mirred action had leftover
debug message.

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".

This patch uses the new features of the kernel's netlink CAN interface
making the bus-error reporting configurable and allowing to retrieve
the CAN TX and RX bus error counters via netlink interface. Here is the
output of my test session showing how to use them:

This patch carries basic infrastructure.
You need to make sure that the proper include/linux/xfrm.h is included
for it to compile.

Modify the parser to keep track of the first of any duplicated attributes,
instead of the last. This is required for VF configuration reporting, where
multiple attributes of the same type are added sequentially.

This adds the required changes to gain access to
the head drop classfull queuing discipline named
pfifo_head_drop. In difference to pfifo or pfifo_fast
this queuing discipline will drop the first packet
in the case of queue congestion. As a result the queue
contain always the freshest packets.

To replace the current a root queueing discipline
for eth0:
$ tc qdisc replace dev eth0 root pfifo_head_drop

And show statistics:
$ tc -s qdisc show dev eth0

Final 2.6.33 version

This patch provides iproute2 facilities to configure 6rd tunnel. To
configure a 6rd tunnel, you need to configure a sit tunnel and set
6rd prefix as following :

  ip tunnel add sit1 mode sit local a.b.c.d ttl 64
  ip tunnel 6rd dev sit1 6rd-prefix xxxx:yyyy::/z

Optionally you can provide a relay prefix :

  ip tunnel 6rd dev sit1 6rd-relay_prefix e.f.g.h/i

Finally you can reset previous tunnel settings :

  ip tunnel 6rd dev sit1 6rd-reset

IPv6 addresses that have IFA_F_SECONDARY set are actually temporary addresses,
hence the IFA_F_TEMPORARY equivalent.  Change the output in this case and
allow filtering on the word "temporary".
Signed-off-by: Brian Haley <brian.haley@hp.com>

Currently you can configure "equalize" and it looks all fine and dandy.
The kernel has the interface defined, but apparently there's never actually
been any implementation for it (only a never merged patch in the 2.4 era).

I'm suggesting to drop the code to give any potential users of this feature
the benefit of receiving a proper error message. I see it unlikely that
this will be implemented in the near future, but if it ever happens
reviving the iproute2 side should be as easy as git revert this patch.
