Add two NLA's that allow configuration of Infiniband node or port GUIDs
by referencing the IPoIB net device set over the physical function. The
format to be used is as follows:
ip link set dev ib0 vf 0 node_guid 00:02:c9:03:00:21:6e:70
ip link set dev ib0 vf 0 port_guid 00:02:c9:03:00:21:6e:78

Add vrf keyword to 'ip link' and 'ip addr' commands (common list code).
Allows:
1. Adding a link to a VRF
$ ip link set NAME vrf NAME
Removing a link from a VRF still uses 'ip link set NAME nomaster'
2. Showing links associated with a VRF:
$ ip link show vrf NAME
3. List addresses associated with links in a VRF
$ ip -br addr show vrf red

This is a feature which was lost during the conversion to netlink
interface: If the device exists and a user tries to change the link
layer address, query the kernel for the old address first and reject the
new one if sizes differ.
This patch adds the same check when setting VF address by assuming same
length as PF device.
Note that at least for VFs the check can't be done in kernel space since
struct ifla_vf_mac lacks a length field and due to netlink padding the
exact size can't be communicated to the kernel.

Add IFLA_VF_TRUST message to trust the VF.
PF can accept some privileged operation from the trusted VF.
For example, ixgbe PF doesn't allow to enable VF promiscuous mode until
the VF is trusted because it may hurt performance.
To trust VF.
# ip link set dev eth0 vf 1 trust on
To untrust VF.
# ip link set dev eth0 vf 1 trust off

Commit 0532555 ('Support "ip link add help" for rtnl_link API') added a
check for specified help parameter. Though due to the place where it has
been added to, it is not possible anymore to force a given parameter to
be interpreted as interface name by prefixing it with 'dev '. Fix this
by forcing whatever follows 'dev' to be presumed as interface name.

This adds support for slightly less output than is normally provided by
'ip link show' and 'ip addr show'. This is a bit better when you have a

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
LAG application to handle split-brain situation on peer-link failure.
Example:
root@net-next:~# ip link set eth1 protodown on
root@net-next:~/iproute2# ip link show eth1
4: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

There have been several instances where response from kernel
has overrun the stack buffer from the caller. Avoid future problems
by passing a size argument.
Also drop the unused peer and group arguments to rtnl_talk.
Add a new option to toggle the ability of querying the RSS configuration of a specific VF.
VF RSS information like RSS hash key may be considered sensitive on some devices where
this information is shared between VF and PF and thus its querying may be prohibited by default.
This new option allows a system administrator with privileges to modify a PF state
to control if the above VF querying is allowed or not.
For example:
To enable RSS querying of VF[0] of ethX:
>> ip link set dev ethX vf 0 query_rss on

This new attribute is now advertised by the kernel for x-netns interfaces.
It's also possible to set it when an interface is created (and thus creating a
x-netns interface with one single message).

$ ip -n foo netns set bar 15
$ ip -n foo link add ipip1 link-netnsid 15 type ipip remote 10.16.0.121 local 10.16.0.249
$ ip -n foo link ls ipip1

This patch avoids a full link wildump request when the user has specified
a single link. Uses RTM_GETLINK without the NLM_F_DUMP flag.
This helps on a system with large number of interfaces.
This patch currently only uses the link ifindex in the filter.
Hoping to provide a subsequent kernel patch to do link dump filtering on
other attributes in the kernel.
In iplink_get, to be safe, this patch currently sets the answer buffer
size to the max size that libnetlink rtnl_talk can copy. The current api
does not seem to provide a way to indicate the answer buf size.
