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.
