Kmod-trelay wifi-to-wifi bridge configuration

Hi,
I followed this thread for wifi-to-eth bridging, trying to adapt it for wifi-to-wifi bridge, but couldn't get it to work.
The two wifi networks do not exchange packets.

Has anyone succeeded in this?

yes, I made it

I debug adapters ( or interface) one by one using tcpdump and printk.

In my environment, eth0.1 needs to enable promiscuous mode,because arp was droped.

ifconfig eth0.1 promisc

I want to find the cause, but the perf is broken.

PS:There is a bad joke , if you debug the bug, then the bug will disappear. just like Double-slit experiment
