tc/netem: fix loss state display and p14 parsing
The display of the entire netem loss state is shown as if it
were gemodel state, as the loss state information is assigned to the
wrong pointer. Correct this by assigning the loss state to the correct
pointer.
Additionally, attempting to set netem loss state will result in
random values in the p14 state probability because the option value
passed to the kernel by tc netem is not parsed or initialized. Fix this
by supplying a default value of 0 for p14 and parsing the p14 value if
one is supplied.

ip: officially support flag mngtmpaddr also for "ip addr del"
Kernel is being extended to support flag IFA_F_MANAGETEMPADDR also for
deletion of addresses. This will allow a userspace application to indicate
that for a global address the kernel should delete all related temporary
addresses as well.
"ip addr del" internally calls ipaddr_modify which silently accepts
any flag provided on the command line already, independent of the
actual command.
Therefore only the usage documentation needs to be extended.
Flags for a peer override flags for the other and not used for the
peer.

iproute: Show default type, table, proto and scope of route
In "ip route show" output unicast type, main table, boot protocol and

Sometimes it is helpful to show the hidden label for people not enough

With this patch "ip route show" with -d option shows the default labels.
Example of difference of output with -d option:

Proportional Integral controller Enhanced (PIE) is a scheduler to address the
bufferbloat problem.
We present here a lightweight design, PIE(Proportional Integral controller
Enhanced) that can effectively control the average queueing latency to a target
value. Simulation results, theoretical analysis and Linux testbed results have
shown that PIE can ensure low latency and achieve high link utilization under
various congestion situations. The design does not require per-packet
timestamp, so it incurs very small overhead and is simple enough to implement
in both hardware and software. "
For more information, please see technical paper about PIE in the IEEE
Conference on High Performance Switching and Routing 2013. A copy of the paper
can be found at ftp://ftpeng.cisco.com/pie/.

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 \

This patch fixes the issue by initializing the two globals when we

xfrm: enable to set non-wildcard mark 0 on SAs and SPs
ip xfrm considers that the user-defined mark is "any" as soon as
(mark.v & mark.m == 0), which prevents from specifying non-wildcard
marks that include the value 0 (typically 0/0xffffffff).
Yet, matching exactly mark 0 is useful for instance to separate
vti policies from global policies.
