This patch adds support to set and display protodown on a switch port. The
switch driver can handle this error state by doing a phys down on the port.
One example user space application setting this flag is a multi-chassis

Example:

Two commands are added:
- ip netns list-id
- ip monitor nsid
A cache is also added to remember the association between the iproute2 netns
name (from /var/run/netns/) and the nsid.
To avoid interfering with the rth socket, a new rtnl socket (rtnsh) is used to
get nsid (we may send rtnl request during listing on rth).
Example:
$ ip netns list-id
nsid 0 (iproute2 netns name: foo)
$ ip monitor nsid
Deleted nsid 0 (iproute2 netns name: foo)
nsid 16 (iproute2 netns name: bar)

- 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.

This attribute is like RTA_DST except it specifies the destination
address to place on a packet when it leaves the host. For ip based
protocols this is destination NAT and not a common part of forwarding.
For protocols like MPLS label swapping is something that typically
happens on every hop.
There is likely to be a RTA_NEWSRC at some point so RTA_NEWDST
is printed as "as to" and can be specified either as "as to"
or just "as"

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.
