[SOLVED][Gentoo] Hostapd + Android 6 + losowy mac-adres?

Cześć

Jest sobie Gentuś w PieCu, ma podpiętą do USB kartę Tp-Link 722N, i udostępnia neta do Nexusa 7 2013 z najnowszym stabilnym Andkiem.

Konfiguracja:
tworzenie mostka:

Kod:

brctl delbr br0 2>/dev/null
iw dev wlan0 interface add wlan0_sta type managed addr ec:08:6b:17:66:e2
iw dev wlan0 interface add wlan0_ap type managed addr ec:08:6b:17:66:e3
ifconfig wlan0 up
brctl addbr br0   2>/dev/null
brctl setfd br0 1 2>/dev/null
brctl addif br0 lan 2>/dev/null
brctl addif br0 wlan0_ap 2>/dev/null
ifconfig br0 192.168.0.1 netmask 255.255.255.0 2>/dev/null
ifconfig br0 up 2>/dev/null
exit 0;

konfig hostpad:

Kod:

interface=wlan0_ap
bridge=br0
driver=nl80211
hw_mode=g
ieee80211n=1
wmm_enabled=1
channel=2
country_code=PL
ieee80211d=1
ssid=test_andka
auth_algs=3
wpa=3
wpa_passphrase=abc98765
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
macaddr_acl=0
ht_capab=[HT20][SHORT-GI-20]
eap_reauth_period=360000000
ignore_broadcast_ssid=0
logger_syslog=-1

Łączy podręcznikowo:

Kod:

Jako że z tym Nexusem włóczę się po różnych dziwnych hotspotach, to zachciało mi się mieć na nim losowy mac adress.

Kidy jednak zmienię mac w Andku w taki sposób:

Kod:

svc wifi disable
busybox ifconfig wlan0 down
busybox ifconfig wlan0 hw ether 6b:69:b6:4e:0e:59
busybox ifconfig wlan0 up
svc wifi enable

to kończą się żarty, a zaczynają schody:

Próbowałem po zmianie macu w Andku zapominać i ponownie dodawać sieć, ale nic nie pomaga,
próbowałem przed odpaleniem sieci w Andku restartować hostpad, kombinowałem jak koń pod górę,  nic nie pomaga.
co ciekawe, w logach hostpad nie ma ani śladu nowego Mac-addresu Andka.

Zastanawiam się, czy do danej sieci jest przypisywany jakiś ticket który jest sprawdzany przy ponownym łączeniu, czy co innego?

Wszelkie uwagi i pomysły mile widziane. ;)

PS:
Różne andkowe wtyczki  typu Pry-FI poległy w takich samych okolicznościach próbując starcia z moim hostapd. ;P


EDIT:
Android 6 ma coś namieszane, na domyślnym romie po odpaleniu [b]svc wifi enable[/b] zmieniał mac na oryginalny, ale nie pokazywał tj zmiany ifconfig, na CyanogenMod-13 [b]svc enable wifi[/b] przywraca oryginalny mac-adress karty.

Pozdro
