Thomas Graf 9f0f7272ac ipv4: AF_INET link address family 
Implements the AF_INET link address family exposing the per
device configuration settings via netlink using the attribute
IFLA_INET_CONF.

The format of IFLA_INET_CONF differs depending on the direction
the attribute is sent. The attribute sent by the kernel consists
of a u32 array, basically a 1:1 copy of in_device->cnf.data[].
The attribute expected by the kernel must consist of a sequence
of nested u32 attributes, each representing a change request,
e.g.
	[IFLA_INET_CONF] = {
		[IPV4_DEVCONF_FORWARDING] = 1,
		[IPV4_DEVCONF_NOXFRM] = 0,
	}

/* ifi_flags.
IFF_* flags.
The only change is:
IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
more not changeable by user. They describe link media
characteristics and set by device driver.
Comments:
- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
- If neither of these three flags are set;
the interface is NBMA.
- IFF_MULTICAST does not mean anything special:
multicasts can be used on all not-NBMA links.
IFF_MULTICAST means that this media uses special encapsulation
for multicast frames. Apparently, all IFF_POINTOPOINT and
IFF_BROADCAST devices are able to use multicasts too.

/* IFLA_LINK.
For usual devices it is equal ifi_index.
If it is a "virtual interface" (f.e. tunnel), ifi_link
can point to real physical interface (f.e. for bandwidth calculations),
or maybe 0, what means, that real media is unknown (usual
for IPIP tunnels, when route to endpoint is allowed to change)
