Not sure why this was limited to ip-link before. It is semantically
equal to the 'master' keyword, which is not restricted at all.

This patch adds a -K / --kill option to ss that attempts to
forcibly close matching sockets using SOCK_DESTROY.
Because ss typically prints sockets instead of acting on them,
and because the kernel only supports forcibly closing some types
of sockets, the output of -K is as follows:
- If closing the socket succeeds, the socket is printed.
- If the kernel does not support forcibly closing this type of
socket (e.g., if it's a UDP socket, or a TIME_WAIT socket),
the socket is silently skipped.
- If an error occurs (e.g., permission denied), the error is
reported and ss exits.

- Pull in the uapi mpls.h
- Update rtnetlink.h to include the mpls rtnetlink notification multicast group.
- Define AF_MPLS in utils.h if it is not defined from elsewhere
as is done with AF_DECnet
The address syntax for multiple mpls labels is a complete invention.
When I looked there seemed to be no wide spread convention for talking
about an mpls label stack in text for. Sometimes people did:
"{ Label1, Label2, Label3 }", sometimes people would do:
"[ label3, label2, label1 ]", and most of the time label
stacks were not explicitly shown at all.
The syntax I wound up using, so it would not have spaces and so it
would visually distinct from other kinds of addresses is.
label1/label2/label3 Where label1 is the label at the top of the label
stack and label3 is the label at the bottom on the label stack.
When there is a single label this matches what seems to be convention
with other tools. Just print out the numeric value of the mpls label.
The netlink protocol for labels uses the on the wire format for a
label stack. The ttl and traffic class are expected to be 0. Using
the on the wire format is common and what happens with other address
types. BGP when passing label stacks also uses this technique with the
exception that the ttl byte is not included making each label in a BGP
label stack 3 bytes instead of 4.

For protocols like MPLS label swapping is something that typically

v2:
Resending now that the dust has cleared in 3.18 on "self" vs. hwmode debate for
brport settings. learning_sync is now set/cleared using "self" qualifier on
brport.
v1:
Add 'learned_sync' flag to turn on/off syncing of learned MAC addresses from
offload device to bridge's FDB. Flag is be set/cleared on offload device port
using "self" qualifier:
$ sudo bridge link set dev swp1 learning_sync on self
$ bridge -d link show dev swp1
2: swp1 state UNKNOWN : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0 state forwarding priority 32 cost 2
hairpin off guard off root_block off fastleave off learning off flood off
2: swp1 state UNKNOWN : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br0
learning on learning_sync on
Adds new IFLA_BRPORT_LEARNED_SYNCED attribute for IFLA_PROTINFO on the SELF
brport.

This permits to selectively enable explicit congestion notification via
the routing table.
If this ecn feature is not set, the kernel will use the tcp_ecn sysctl
to decide wheter to use ECN when establising a TCP connection.
At the time of this writing, the kernel supports ecn and allfrags, but
allfrags is of dubious value and not implemented here.
Example:
ip route change 192.168.2.0/24 dev eth0 features ecn

o "min_tx_rate" option has been added for minimum Tx rate. Hence, for
consistent naming, "max_tx_rate" option has been introduced for maximum
Tx rate.
o Change in v2: "rate" can be used along with "max_tx_rate".
When both are specified, "max_tx_rate" should override.
o Change in v3:
* IFLA_VF_RATE: When IFLA_VF_RATE is used, and user has given only one of
min_tx_rate or max_tx_rate, reading of previous rate limits is done in
userspace instead of in kernel space before ndo_set_vf_rate.
* IFLA_VF_TX_RATE: When IFLA_VF_TX_RATE is used, min_tx_rate is always read
in kernel space. This takes care of below scenarios:
(1) when old tool sends "rate" but kernel is new (expects min and max)
(2) when new tool sends only "rate" but kernel is old (expects only "rate")
o Change in v4 as suggested by Stephen Hemminger:
* As per iproute policy, input and output formats should match. Changing display
of max_tx_rate and min_tx_rate options accordingly.

When configuring a system with multiple network uplinks and default routes, it
is often convenient to reference a routing table multiple times - but reject
its routing decision if certain constraints are not met by it.
Consider this setup:
$ ip route add table secuplink default via 10.42.23.1
$ ip rule add pref 100 table main suppress_prefixlength 0
$ ip rule add pref 150 fwmark 0xA table secuplink
With this setup, packets marked 0xA will be processed by the additional routing
table "secuplink", but only if no suitable route in the main routing table can
be found. By suppressing entries with a prefixlength of 0 (or less), the
default route (/0) of the table "main" is hidden to packets processed by rule
100; packets traveling to destinations via more specific routes are processed
as usual.
It is also possible to suppress a routing entry if a device belonging to
a specific interface group is to be used:
$ ip rule add pref 150 table main suppress_group 1

This patch allows setting VXLAN destination to unicast address.
It allows that VXLAN can be used as peer-to-peer tunnel without
multicast.
v6: change back to the v3 except for using new attribute because
replacing command-line parameters breaks existing scripts,
based by Cong Wang's comments.
v5: rebase on the latest.
v4: replace "group" with "remote" based by David Stevens's comments.
v3: move a new attribute REMOTE into the last of an enum list
based by Stephen Hemminger's comments.
fix the usage to show explicitly that both "remote" and "group"
cannot be specified, based by Ben Hutchings's comments.
v2: use a new argument "remote" instead of "group" based by
Stephen Hemminger's comments.

These do nothing on an 80-column display. They were clearly somebody's
boilerplate way of setting up hanging indents, but the syntax lines
are way too short to require them. And since most were argumentless
they would have been no-ops on any sized display.
The ip link command line help and the ip-link.8.in
man page are outdated in regards to the vxlan support.
The patch updates both the command line help for the
ip command and its man page.
