 *   Roaming ability of eSTA is implemented by Roaming Manager Component and
 *   described in "Roaming Manager module LLD" document, and by
 *   AP Connection module. AP Connection module implemented as two sub-modules.
 *   The major one is AP Connection, that is responsible for:
 *   - providing Roaming Manager with access to other parts of WLAN Driver,
 *   - implementing low levels of roaming mechanism.
 *   Current BSS sub-module takes care of:
 *   - maintaining database of current AP info,
 *   - providing access to database of current AP info.
 *   The Current BSS represents the BSS we are currently connected to.
 *   Among other parameters, it holds the capabilities of the current AP,
 *   its ID and its quality.
 *   When FW indicates 'Out of Sync' event, Current BSS module is responsible
 *   for awaking the device, sending unicast Probe request, waiting for
 *   response and - in case FW comes to the conclusion that there was
 *   no response - for triggering "Beacon missed" to AP Connection module.
 *   In eSTA5.0 FW updates and checks the quality of the connection with
 *   current AP. Current BSS module is responsible to handle event of type
 *   'Low RSSI' from FW. Third type of roaming event reported by FW is
 *   'Consecutive no ack on TX", and it is handled as well by Current
 *   BSS module.Upon reception of any roaming event from FW, Current BSS
 *   module is transferring this event to the AP Connection module in case
 *   of BSS connection, or to SME module in case of IBSS connection.
 *   When WLAN driver is working in IBSS mode, Current BSS module is holding
 *   the parameters of BSS (channel, band, SSID etc.).
 *                                                                          *

DESCRIPTION: Called when receiving beacon or Probe response from current AP
             updates SNR and RSSI in siteMgr and calls apConn in case

            bAveragedData - indicate whether the given SNR,RSSI are already averaged.
                            This is done since this values can be given directly from the
                            Fw, which average those values.
