  SVN rev 184302 on 2008-10-26 21:56:27Z by sam
  
  Fix joining an 11b BSS: scanning is normally done using 11g channels
  (unless explicitly locked to mode 11b) so when we join the bss the
  channel attached to the scan cache entry may need to be demoted.
  
  o demote to 11b if the ap is advertising 11b rates
  o skip the ap if it's 11b but we're locked to 11g (could consider this
    advisory but for now treat it as mandatory)
  o handle an odd edge case, if there is a fixed transmit rate for 11g
    then the rate check against the 11b ap will fail, try to demote to
    11b and retry the rate check
