It must be the bssid of the peer; it is used to form the 4-address frames.

That brief description was a big help in itself, thank you.
One question: should the BSSID in the legacy mode be the same as the
MAC address of the main WDS node? Or can it be a random number?
thanks,

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.
