rt61pci &kernel-2.6.30-rc7&nl80211 driver

[Andrzej Kosmala]

When I tried on linux-2.6.29.4 I've got:
./hostad hostapd.config:
Configuration file: hostapd.config
nl80211: Could not add multicast membership for scan events: -2 (No such 
file or directory)
nl80211 driver initialization failed.
On this mailing list I found that kernel 2.6.30 is needed and now I've 
2.6.30-rc7.
 
./hostapd hostapd.config:
Configuration file: hostapd.config
ioctl[SIOCSIFFLAGS]: No such file or directory
nl80211 driver initialization failed.
ELOOP: remaining socket: sock=3 eloop_data=0x93c9860 user_data=0x93c9d58 
handler=0x8078180

On both kernels iwconfig wlan0:
wlan0     IEEE 802.11bg  Mode:Master  Frequency:2.412 GHz  Tx-Power=0 dBm  
          Retry min limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

cat hostapd.config:
interface=wlan0
driver=nl80211
dump_file=/tmp/hostapd.dump
ssid=test

Where is my mistake? why is it not working?
