The NLMSG_PUT() macro contains a hidden goto which makes the code hard
to audit and very error prone.

While been there also use the inline function nlmsg_data() instead of the
NLMSG_DATA() macro to do explicit type checking.

The AT86RF231 is a feature rich, low-power 2.4 GHz radio transceiver
designed for industrial and consumer ZigBee/IEEE 802.15.4, 6LoWPAN,
RF4CE and high data rate 2.4 GHz ISM band applications.

This patch adds support for the Atmel RF230/231 radio transceivers.

Every real 802.15.4 transceiver, which works with software MAC layer,
can be classified as a wpan device in this stack. So the wpan device
implementation provides missing link in datapath between the device
drivers and the Linux network queue.

According to the IEEE 802.15.4 standard each packet can be one of the
following types:
 - beacon
 - MAC layer command
 - ACK
 - data

This patch adds support for the data packet-type only, but this is
enough to perform data transmission and receiving over radio.

Fix to allow IPv6 packets originating locally to match rules with the "iff"
set to "lo".  This allows IPv6 rule matching work the same as it does for
IPv4.  From the iproute2 man page:

   iif NAME
		  select  the incoming device to match.  If the interface is loop‐
		  back, the rule only matches packets originating from this  host.
		  This  means that you may create separate routing tables for for‐
		  warded and local packets and, hence, completely segregate them.
