This patch adds a basic nl802154 framework. Most of this code was
grabbed from nl80211 framework.

Phoebe Buckheister 3e9c156e2c ieee802154: add netlink interfaces for llsec
This patch adds user-visible interfaces for the llsec infrastructure.
For the added methods, the only major difference between all add/remove
implementation lies in how the specific object is parsed, and for dump
requests, how objects are written into netlink messages.

To save on boilerplate code, table dumps are routed through a helper
function that handles netlink dump state, leaving the actual dumping
code to care only about iterating over the table to be dumped and
filling netlink messages. For add/remove methods, the boilerplate
required to work is not quite as large, but still enough to also move
into a local helper.

Phoebe Buckheister e462ded699 mac802154: make csma/cca parameters per-wpan
Commit 9b2777d608 (ieee802154: add TX power control to wpan_phy)
and following erroneously added CSMA and CCA parameters for 802.15.4
devices as PHY parameters, while they are actually MAC parameters and
can differ for any two WPAN instances. Since it is now sensible to have
multiple WPAN devices with differing CSMA/CCA parameters, make these
parameters MAC parameters instead.

Phoebe Buckheister 9b2777d608 ieee802154: add TX power control to wpan_phy
Replace the current u8 transmit_power in wpan_phy with s8 transmit_power.
The u8 field contained the actual tx power and a tolerance field,
which no physical radio every used. Adjust sysfs entries to keep
compatibility with userspace, give tolerances of +-1dB statically there.

This patch only adds support for this in the at86rf230 driver and the
RF212 chip. Configuration calculation for RF212 is also somewhat basic,
but does the job - the RF212 datasheet gives a large table with
suggested values for combinations of TX power and page/channel, if this
does not work well, we might have to copy the whole table.

Johannes Berg 2a94fe48f3 genetlink: make multicast groups const, prevent abuse
Register generic netlink multicast groups as an array with
the family and give them contiguous group IDs. Then instead
of passing the global group ID to the various functions that
send messages, pass the ID relative to the family - for most
families that's just 0 because the only have one group.

This avoids the list_head and ID in each group, adding a new
field for the mcast group ID offset to the family.

At the same time, this allows us to prevent abusing groups
again like the quota and dropmon code did, since we can now
check that a family only uses a group it owns.

Johannes Berg 1c582d915d ieee802154: use genl_register_family_with_ops()
This simplifies the code since there's no longer a need to
have error handling in the registration.

Unfortunately it means more extern function declarations are
needed, but the overall goal would seem to justify this.

While at it, also fix the registration error path - if the
family registration failed then it shouldn't be unregistered.
