From my quick search, many of the older ones.
The list is quicker if we talk about the ones that *do* have it:
ath(4)
run(4)
mwl(4)
ndis(4)
wi(4)
It looks like the capabilities struct defines that the driver/hardware
will provide to wpa_supplicant.
Using the pre-2.0 wpa_supplicant seems to work with iwn(4) as well.
