No promises, but I'd like to take a look at WDS,
since I just got another prism54.

There is one problem - I don't know what WDS is
supposed to do, because I use WDS link with hostap driver
in a awkward way - I *turn off* AP bridging.
This turns AP into kind of multihomed pseudo ethernet
device which does NOT automatically forward packets
from one STA to another (it is done via normal IP routing
instead). In this setup, logically WDSes are just another
devices, distinct from AP:

+--------------+        +AP-+
|  core kernel |<-------| < | <--------- STA1
|(does routing)|------->| > | ---------> STA2
|              |        +---+
|              |        +WDS+
|              |<------>|<->| <--------> WDS peer
+--------------+        +---+

I suspect that most other people do not disable bridging.
For them WDS cannot be a separate device... or what?
I'm lost here.

Let's imagine three APs linked with WDS (double links
in a picture below):

sta1 <---> AP1 <===> AP2 <===> AP3 <---> sta2

Say, sta1 wants to sent a packet to sta2.
What should happen?
