The firmware sends the frame, hostapd receives it, and is discarded
due to the check you pointed out. I am working in a translator, so
instead of dropping it will transform the frame, i.e.,  take out the 4
address. I will post the code once I tested it and it is stable.

I know. I create the wds links myself, problem is that whe hostap is
launched, it mantains its own list of associated STA.

Yes? I will look into previous posts. The problem here resides in
force the other party into creating the wds link. My way of doing it
is:

1-Scan in Managed mode
2-If Mesh eSSID found create WDS link
3-Associate in Manage mode
4-Change to Master mode
5-Begin WPA exchange

Problem resides in how the other party creates the WDS links. If you
do it yourself, hostapd never understand that this party is
associated, Thats why I have to associate in Managed modem so hostapd
will add the MAC STA to its list.
