It served no purpose: we never call it from anywhere in the stack
and the only driver that did implement it (fakehard) merely provided
a dummy value.

There is also considerable doubt whether it would make sense to
even attempt beacon processing at this level in the Linux kernel.

According IEEE 802.15.4 standard each node can be either full functionality
device (FFD) or reduce functionality device (RFD). So 2 sets of operations
are needed. This patch declare RFD operations structure.

ops->get_phy should increment reference to wpan-phy. As we return
the external structure, we should do refcounting correctly.

IEEE 802.15.4-2006 adds new concept: channel pages, which can contain several
channels. Add support for channel pages in the API and in the fakehard driver.

Add support for communication over IEEE 802.15.4 networks. This implementation
is neither certified nor complete, but aims to that goal. This commit contains
only the socket interface for communication over IEEE 802.15.4 networks.
One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data
inside normal IEEE 802.15.4 packets.

Configuration interface, drivers and software MAC 802.15.4 implementation will
follow.

Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel
Smolensky as a research project at Siemens AG. Later the stack was heavily
reworked to better suit the linux networking model, and is now maitained
as an open project partially sponsored by Siemens.
