 * \var g_phy_rates_suppt
 *
 * \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 bools (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 = g_phy_rates_suppt[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.
 *
