992: ##### Multiple BSSID support ##################################################
993: #
994: # Above configuration is using the default interface (wlan#, or multi-SSID VLAN
995: # interfaces). Other BSSIDs can be added by using separator 'bss' with
996: # default interface name to be allocated for the data packets of the new BSS.
997: #
998: # hostapd will generate BSSID mask based on the BSSIDs that are
999: # configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
1000: # not the case, the MAC address of the radio must be changed before starting
1001: # hostapd (ifconfig wlan0 hw ether <MAC addr>).
1002: #
1003: # BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
1004: # specified using the 'bssid' parameter.
1005: # If an explicit BSSID is specified, it must be chosen such that it:
1006: # - results in a valid MASK that covers it and the dev_addr
1007: # - is not the same as the MAC address of the radio
1008: # - is not the same as any other explicitly specified BSSID
1009: #
1010: # Please note that hostapd uses some of the values configured for the first BSS
1011: # as the defaults for the following BSSes. However, it is recommended that all
1012: # BSSes include explicit configuration of all relevant configuration items.
