this is a new chipset which is not yet supported by openbsd.

it's a common problem with newer atheros chipsets - all of them are
detected as AR5212, even if they're based on AR5213 or AR5214 MAC
chips. but this doesn't matter, the MAC is mostly compatible to the
ar5212. the main problem is the new rf2112 radio chipset and probably
the new PHY revision.

supported examples of the ar5212:

ath0: AR5212 5.6 phy 4.1 rf5111 1.7 rf2111 2.3	(AR5212)
ath0: AR5212 5.9 phy 4.3 rf5112 3.6		(AR5213)

currently unsupported:

ath0: AR5212 7.9 phy 4.5 rf2112 5.6 rf2112 5.6
