'Hide ESSID' doesn't Hide the ESSID (OpenWRT/WRT1900AC)

[Malathion]

Occurs on multiple builds of OpenWRT and it does not appear to be a Luci issue. Now using r45711. First thing I did on a fresh install of generic was disable the SSIDs on both radios. I still see the broadcasted SSIDs, even after a powercycle.

config wifi-device 'radio0' option type 'mac80211' option hwmode '11g' option path 'soc/soc:pcie-controller/pci0000:00/0000:00:02.0/0000:02:00.0' option country 'US' option channel 'auto' option htmode 'HT40' option txpower '20'

config wifi-iface option device 'radio0' option network 'lan' option mode 'ap' option ssid '*_' option encryption 'psk2+ccmp' option key '_**' option hidden '1'

config wifi-device 'radio1' option type 'mac80211' option channel '36' option hwmode '11a' option path 'soc/soc:pcie-controller/pci0000:00/0000:00:03.0/0000:03:00.0' option htmode 'VHT80' option country 'US' option txpower '17'

config wifi-iface option device 'radio1' option network 'lan' option mode 'ap' option ssid '**_' option encryption 'psk2+ccmp' option key '_**'

option hidden '1'

If it helps anyone... I was able to get ssid hiding to work by making this one-line code change to mwl_mac80211.c I changed line 870 from; if ((info->ssid[0] != '\0') && (info->ssid_len != 0)) to; if ((info->ssid[0] != '\0') && (info->ssid_len != 0) && !info->hidden_ssid)

Thanks. The fix is committed.
