/**
 * \var gPhyRatesSuppt
 *
 * \brief Rate support lookup table
 *
 *
 * This is a  lookup table indexing rates &  configuration parameters to
 * support.  Given a rate (in  unites of 0.5Mpbs) & three booleans (MIMO
 * Enabled, Channel  Bonding Enabled, & Concatenation  Enabled), one can
 * determine  whether  the given  rate  is  supported  by computing  two
 * indices.  The  first maps  the rate to  table row as  indicated below
 * (i.e. eHddSuppRate_6Mbps maps to  row zero, eHddSuppRate_9Mbps to row
 * 1, and so on).  Index two can be computed like so:
 *
 * \code
   idx2 = ( fEsf  ? 0x4 : 0x0 ) |
          ( fCb   ? 0x2 : 0x0 ) |
          ( fMimo ? 0x1 : 0x0 );
 * \endcode
 *
 *
 * Given that:
 *
 \code
   fSupported = gPhyRatesSuppt[idx1][idx2];
 \endcode
 *
 *
 * This table is based on  the document "PHY Supported Rates.doc".  This
 * table is  permissive in that a  rate is reflected  as being supported
 * even  when turning  off an  enabled feature  would be  required.  For
 * instance, "PHY Supported Rates"  lists 42Mpbs as unsupported when CB,
 * ESF, &  MIMO are all  on.  However,  if we turn  off either of  CB or
 * MIMO, it then becomes supported.   Therefore, we mark it as supported
 * even in index 7 of this table.
 *

/**
 * \brief Enquire as to whether a given rate is supported by the
 * adapter as currently configured
 *
 *
 * \param nRate A rate in units of 500kbps
 *
 * \return TRUE if  the adapter is currently capable  of supporting this
 * rate, FALSE else
 *
 *
 * The rate encoding  is just as in 802.11  Information Elements, except
 * that the high bit is \em  not interpreted as indicating a Basic Rate,
 * and proprietary rates are allowed, too.
 *
 * Note  that if the  adapter's dot11Mode  is g,  we don't  restrict the
 * rates.  According to hwReadEepromParameters, this will happen when:
 *
 *   ... the  card is  configured for ALL  bands through  the property
 *   page.  If this occurs, and the card is not an ABG card ,then this
 *   code  is  setting the  dot11Mode  to  assume  the mode  that  the
 *   hardware can support.   For example, if the card  is an 11BG card
 *   and we  are configured to support  ALL bands, then  we change the
 *   dot11Mode  to 11g  because  ALL in  this  case is  only what  the
 *   hardware can support.
