Hi All
I have created Dynamic vlan in Wifi network.And according to station mac 
address a particular vlan is assigning.Stations who  are in a same vlan is 
communicating with each other. Now the problem is, whenever i am assigning 
a particular station to another vlan then bridging is not working(brctl 
refusing the virtual wlan0 interface).
I am configuring the hostapd like below
/etc/hostapd/hostapd.conf   file contains 

ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
interface=wlan0
driver=nl80211
channel=6
hw_mode=g
ssid=xyz
dynamic_vlan=1
vlan_file=/etc/hostapd/hostapd.vlan
vlan_tagged_interface=eth0
macaddr_acl=1
accept_mac_file=/etc/hostapd/hostapd.accept

/etc/hostapd/hostapd.vlan file contains

# VLAN ID to network interface mapping
10    wlan0.10
20    wlan0.20
*      wlan0.#

/etc/hostapd/hostapd.accept file contains

84:c9:b2:76:07:c9 10
1c:6f:65:db:ff:2d 10
bc:77:37:17:8e:64 20
00:21:5c:8b:00:4f 20

After this i am running hostapd and it is working fine and it created vlan 
bridged interface brvlan10 and brvlan20.After assigning the ip addresses 
for both the interfaces ,successfully working
Here the problem comes when i am modify  the hostapd.accept file like 
below

84:c9:b2:76:07:c9 20
1c:6f:65:db:ff:2d 10
bc:77:37:17:8e:64 10
00:21:5c:8b:00:4f 20

i.e i have assigned the mac addresses into different vlan then brctl 
refusing the wireless interface(wlan0.10 and wlan0.20) from brvlan10 and 
brvlan20.And station is not able to connect the AP.
Please can anyone tell me why these problem is happening

Thanks and Regards
Suman Pandit
