Other BSSIDs can be added by using separator 'bss' with 1605# default interface name to be allocated for the data packets of the new BSS. 1606# 1607# hostapd will generate BSSID mask based on the BSSIDs that are 1608# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is 1609# not the case, the MAC address of the radio must be changed before starting 1610# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for 1611# every secondary BSS, this limitation is not applied at hostapd and other 1612# masks may be used if the driver supports them (e.g., swap the locally 1613# administered bit) 1614# 1615# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is 1616# specified using the 'bssid' parameter. 1617# If an explicit BSSID is specified, it must be chosen such that it: 1618# - results in a valid MASK that covers it and the dev_addr 1619# - is not the same as the MAC address of the radio 1620# - is not the same as any other explicitly specified BSSID 1621# 1622# Please note that hostapd uses some of the values configured for the first BSS 1623# as the defaults for the following BSSes.
