-Add network specific BSSID black and white lists
-
-This change adds the configuration options "bssid_whitelist" and
-"bssid_blacklist" used to limit the AP selection of a network to a
-specified (finite) set or discard certain APs.
-
-This can be useful for environments where multiple networks operate
-using the same SSID and roaming between those is not desired. It is also
-useful to ignore a faulty or otherwise unwanted AP.
-
-In many applications it is useful not just to enumerate a group of well
-known access points, but to use a address/mask notation to match an
-entire set of addresses (ca:ff:ee:00:00:00/ff:ff:ff:00:00:00).
-
-This change expands the data structures used by MAC lists to include a
-mask indicating the significant (non-masked) portions of an address and
-extends the list parser to recognize mask suffixes.
