VLAN dynamic interface down

Hi,
I've setup a small configuration to let hostapd created dynamic
interface using the dynamic_vlan functionality as the follow :
logger_syslog=-1
logger_syslog_level=1
logger_stdout=-1
logger_stdout_level=2
dump_file=/var/run/hostapd-wlan0.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
interface=wlan0
driver=nl80211
ssid=Scabb Island
ieee80211d=1
country_code=FR
hw_mode=g
channel=1
beacon_int=100
dtim_period=10
ignore_broadcast_ssid=0
wmm_enabled=0
auth_algs=1
wpa=2
wpa_passphrase=XXXXXX
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
dynamic_vlan=1
vlan_file=/etc/hostapd/vlan.lst
accept_mac_file=/etc/hostapd/accept.lst
/etc/hostapd/vlan.lst contain the following :
* vlan#
Interface vlanX is correctly created but remain DOWN :
# ip link show dev vlan34
44: vlan34: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 00:1b:b1:03:70:6a brd ff:ff:ff:ff:ff:ff
So hostapd fail to add STA to freshly created interface :
nl80211: NL80211_ATTR_STA_VLAN (addr=5c:0a:5b:25:9d:a7 ifname=vlan34 vlan_id=34) failed: -100 (Network is down)
wlan0: STA 5c:0a:5b:25:9d:a7 IEEE 802.11: could not bind the STA entry to vlan_id=34
If I manually set up iface vlan34, all is fine, but I would like not to
do this.
Looking for this on Google seems to explain that this dynamic iface
should be a bridge, but it's not :
# ethtool -i vlan34
driver: ath5k
version: 3.1.10-allin1
firmware-version: N/A
bus-info: 0000:00:0c.0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
Is something wrong ? I'm using hostapd v1.0 :
# hostapd -v
hostapd v1.0
User space daemon for IEEE 802.11 AP management,
IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
Copyright (c) 2002-2012, Jouni Malinen <j at w1.fi> and contributors
I include a log file generated by launching hostapd as the follow :
# hostapd -dd -K -P /var/run/hostapd-wlan0.pid /etc/hostapd/wlan0.conf
I volontary suppressed all 'Add randomness' lines as really annoying and also masked PSK.
Regards,
