   4 Subject: [PATCH] brcmfmac: disable MBSS feature for bcm4330 device
   5
   6 The MBSS feature was already disabled for bcm43362 as it resulted in a
   7 beacon with BRCM_TEST_SSID regardless user configuration in hostapd. Now
   8 the same has been reported for bcm4330 so disable the feature for this
   9 device as well.
