====================
ieee802154: support rf212 and extended mac features

this patch set adds support for the RF212 radio chip to the existing
at86rf230 driver and adds support for numerous features of the RF212
chips to the ieee802154 stack. These features include CSMA parameter
configuration, transmit power control, CCA parameter configuration, and
automatic retransmission of frames. Netlink APIs are provided for all
new options introduced in this set.

Many features might also work for RF230, but since I have no such chips
at my disposal, most new features are implemented only for RF212.

Changes since v2:
 * Indentation
Changes since v1:
 * CodingStyle compliance. Thanks Sergei Shtylyov
 * Add CSMA parameters to netlink phy list that were forgotten in v1
====================
