Hi!

Here is last week's status. I added a simple per vap ratectl statistics api
and put capabilities into it:

* add struct ieee80211_rc_stat to track per vap ratectl statistics.
* change the interface of __init__ and __node_init__. update the callers.
* add ieee80211_ratectl_update_stat() to update the per vap rc statistics.
  it called by __complete__ of rc algo.
* drop struct ieee80211_ratectl_node and port irn_capabilities to
  irs_capabilities in struct ieee80211_rc_stat. update the rc api and rc
  algorithms (amrr and sample), update micros that check cap using the
  capabilies field.

Thanks!
