Aloha,
I'm trying to get WDS running - I am working my way through the stuff
in /usr/src/tools/tools/net80211/scripts, but it really only gives
examples and doesn't explain the why of it - is there a more verbose
how to somewhere that would help me understand this?
I've written nothing. You say the "why" is missing but you don't ask
any questions.
There are 2 flavors of wds, legacy and dynamic. The legacy stuff is
trivial to setup;
ifconfig wlan create wlandev ath0 wlanmode wds wlanbssid ... wdslegacy
The bssid is the peer's mac address. This is just a fixed 4-address
conduit for frames. There must be an ap vap already created. You want
to plumb the vap into a bridge or assign it an ip address and route (not
sure about routing; I always use it bridged).
Dynamic wds setup depends on whether you're on the ap side or the sta
side; the scripts are the best examples. The idea is you have a sta-ap
association that carries 4-address traffic. Because there's a
full-blown association you get discovery, roaming, and security for
free. This is what you'll find in Apple's ap products though they've
done a bunch of work to make it more production-quality.
Note that wds is implemented above the drivers (modulo a bit of glue
code). ath is just one driver that supports wds, ral is another.
