Adrian Chadd 2d20d6559d Add a per-node rate control routine for each rate control module.
For now, the only module implement is 'sample', and that's only partially
implemented.  The main issue here with reusing this structure in userland
is that it uses 'rix' everywhere, which requires the userland code to
have access to the current HAL rate table.

For now, this is a very large work in progress.

Specific details:

* The rate control information is per-node at the moment and wrapped
  in a TLV, to ease parsing and backwards compatibility.
* .. but so I can be slack for now, the userland statistics are just
  a copy of the kernel-land sample node state.
* However, for now use a temporary copy and change the rix entries
  to dot11rate entries to make it slightly easier to eyeball.

Problems:

* The actual rate information table is unfortunately indexed by rix
  and it doesn't contain a rate code.  So the userland side of this
  currently has no way to extract out a mapping.

TODO:

* Add a TLV payload to dump out the rate control table mapping so
  'rix' can be turned into a dot11 / MCS rate.
* .. then remove the temporary copy.
