WL1837MOD: Does wl18xx firmware support WDS/4addr mode?

Part Number: WL1837MOD

Hi,

I am trying to set up a wifi-ethernet bridge in an RTOS using fw 8.9.0.0.86 and trying to use wds/4addr mode. 

What I am seeing is that receive packets with the WL18xx as the Receiver Address (RA) are not being passed to the host. Packets with the WL18xx as the Source Address (SA) are passed to the host as expected. 

So questions are:

1 does fw support receiving 4 address mode packets where the WL18xx is the RA? I can't find any reference to this in the manuals or linux code.

2 if it does, how should this be enabled?

Current test setup is trying to run DHCP from ethernet interface over wifi to AP.

DHCP Discover can be seen in wireshark sniffer being transmitted to AP with correct 4 addr header

DHCP Offer can be seen in wireshark sniffer from the AP, again with correct 4addr header .

However, the packet is not received at the host.

Thanks, Iain
