- Use standard notation for units

Rephrasing for clarity.

Note that in ip-rule.8 I rephrased a sentence to "The RPDB is scanned
in order of decreasing priority." The original version talked about
*in*creasing priority, but from the context that didn't make sense.

On openSUSE 12.2 (at least) xtables.h is not installed in the system-wide
include dir but in /usr/include/iptables-1.4.16.3/. This results in the
following build failure:
em_ipset.c:26:21: fatal error: xtables.h: No such file or directory

Other includers of xtables.h already call out to pkg-config

Don't put it on separate line, keep it on line with link address.

This is useful to know the 'real' status of an interface (the flag IFF_PROMISC
is exported by the kernel only when the user set it explicitly, for example it
will not be exported when a tcpdump is running).

This information will be displayed when '-details' is provided by the user.

Example:
$ ip -d l l tun10
6: tun10: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN mode DEFAULT
    link/sit 10.16.0.249 peer 10.16.0.121

The 'inherit/STRING' or 'inherit/00..ff' syntax indicates that the
TOS field of tunneled packets should be copied from the original IP
header, but for non-IP packets the value STRING or 00..ff should be
used instead. (This syntax is already used by 'ip tunnel show'.)

Also clarify the man page and the command usage text (particularly
that the TOS is not specified as a decimal number).

Sometimes "ip netns delete" fails because it can not delete the file a
network namespace was mounted on.  If this only happened when a
network namespace was really in use this would be fine, but today it
is possible to pin all network namespaces by simply having a long
running process started with "ip netns exec".

Every mount is copied when a network namespace is created so it is
impossible to prevent the mounts from getting into other mount
namespaces.  Modify all mounts in the files and subdirectories of
/var/run/netns to be shared mount points so that unmount events can
propogate, making it unlikely that "ip netns delete" will fail because
a directory is mounted in another mount namespace.

Ben Hutchings pointed out that the return value of do_netns is passed
to exit and the current convention of returning -1 for failure is
inconsitent with that reality.

Return EXIT_FAILURE instead of -1 and EXIT_SUCCESS instead of 0.  To make
it clear that the return codes are expected to be passed to exit.

Some systems are now following the advice in
linux/Documentation/sharedsubtrees.txt and running with all mount
points shared between all mount namespaces by default.

After creating the mount namespace call mount on / with
MS_SLAVE|MS_REC to modify all mounts in the new mount namespace to
slave mounts if they are shared or private mounts otherwise.
Guarnateeing that changes to the mount namespace created with
"ip netns exec" don't propgate to other namespaces.

	configure: move toolchain init to a function

Script has lots of shell functions but never indented properly.

Commit v3.7.0~10 caused the variable new PKG_CONFIG variable never
to be present at the time of calling make, leading to tc/m_xt.so
not linked with -lxtables (result from pkg-config xtables --libs),
that in turn leading to

tc: symbol lookup error: /usr/lib64/tc//m_xt.so: undefined symbol:
xtables_init_all

mroute was using /proc/net/ip_mr_[vif|cache] to display mroute entries. Hence,
only RT_TABLE_DEFAULT was displayed and only IPv4.
With rtnetlink, it is possible to display all tables for IPv4 and IPv6. The output
format is kept. Also, like before the patch, statistics are displayed when user specify
the '-s' argument.

The patch also adds the support of 'ip monitor mroute', which is now possible.
