Consider the case where multiple BSSes are started with single hostapd
instance i.e., after adding few 'bss' and 'ssid' variables to
single hostapd.conf. Here, just stopping the hostapd doesn't work if one
wants to stop one of the active BSSes.

eg., Lets say there are three BSSes running

wlan0 (test), wlan1 (test1) and wlan2 (test2)

If we want to bring down the test1 bss, then one can do so by
ifconfig wlan1 down

And to re-enabled the test1 BSS.
ifconfig wlan1 up

This will help users to enable/disable/re-enabled of BSSes without
killing/reloading the hostapd.
