  Log:
  SVN rev 185482 on 2008-11-30 19:06:35Z by sam
  
  Major overhaul:
  o eliminate private state indexed by 802.11 rate codes; use the hal's
    rate tables directly to get the same info
  o calculate a mask of operational rates to optimize lookups and checks
    (instead of using for loops and similar)
  o optimize size bin operations
  o ignore rates marked as "do not use" in the hal phy tables
  o fix bug that caused upshifting to break in 11g once the rate dropped
    below 11Mb/s
  o add more intelligent multi-rate tx schedules
  o add support for 1/2 and 1/4 width channels
  o add dev.ath.X.sample_stats sysctl to dump runtime statistics to the console
    (needs to go up to a user app)
  o export more tuning knobs via sysctls (still a couple of magic constants)
