 *   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.
 *                                                                          *
