hostapd with nl80211 bridge problems.

[Andrew T]

Hi,
I just started using hostapd for my AP. I am very happy with the way it 
works but have 1 issue.
My AP is made up of
2.6.26-rc8 kernel with mac80211 and a ralink rt73usb.
009-allow-ap-vlan-modes.patch
Hostapd 0.6.3 and libnl 1.1

My problem is when I try to bridge the wlan0 to eth0 interface wpa is 
failing.

What works:
Hostapd without the bridge works fine with WPA-PSK if I use iptables to 
do NAT on the wireless interface it works well.

Hostapd in the bridge With no encryption. WPA-PSK turned off. works well 
same as above but no need for iptables.

Both the bridge and wpa-psk doesnt work. From my limited knowledge it 
looks like Hostapd doesnt see the EAPOL packets coming in from the bridge.

I do have bridge=br0 set in the config but its like hostapd ignores this 
setting. I can see the replies come in from the client to the bridge but 
hostapd does not see them.

I use wire shark to monitor the bridge while trying to connect so I know 
the EAPOL reply is coming back into the bridge and lost there.

I am open to all suggestions.
