  87  *                      and the plugin to evolve independently.
  88  *
  89  *      wd_bssid        Current associated BSSID (or IBSSID), used when
  90  *                      generating data packet headers for transmission.
  91  *
  92  *      wd_opmode       Current operation mode; any ieee80211_opmode is
  93  *                      supported.
  94  *
  95  *      wd_secalloc     Current allocation policy for security-related
  96  *                      WiFi headers, used when generating packets for
  97  *                      transmission.  The plugin will allocate header
  98  *                      space for the security portion, and fill in any
  99  *                      fixed-contents fields.
 100  *
 101  *      wd_qospad       Generally, QoS data field takes 2 bytes, but
 102  *                      some special hardwares, such as Atheros, will need the
 103  *                      802.11 header padded to a 32-bit boundary for 4-address
 104  *                      and QoS frames, at this time, it's 4 bytes.
