Well, it seems nl80211_set_master_mode() calls send_and_recv_msgs()
and then nl_recvmsgs(0x58cf0, 0x5b2f8) fails with -95 (-EOPNOTSUPP).

sendmsg(4, {msg_name(12)={sa_family=AF_NETLINK, pid=0, groups=00000000},
 msg_iov(1)=[{"\x24\x00\x00\x00\x11\x00\x05\x00\x2f\xf5\x47\x49\xd0\x01\x00\x00\x06\x00\x00\x00\x08\x00\x03\x00\x03\x00\x00\x00\x08\x00\x05\x00\x03\x00\x00\x00"..., 36}],
 msg_controllen=0, msg_flags=0}, 0) = 36

recvmsg(4, {msg_name(12)={sa_family=AF_NETLINK, pid=0, groups=00000000},
 msg_iov(1)=[{"\x24\x00\x00\x00\x02\x00\x00\x00\x5d\xf6\x47\x49\xd7\x01\x00\x00\xa1\xff\xff\xff\x24\x00\x00\x00\x11\x00\x05\x00\x5d\xf6\x47\x49\xd7\x01\x00\x00"..., 4096}],
msg_controllen=0, msg_flags=0}, 0) = 36

$ grep -lr -- -EOPNOTSUPP drivers/net/wireless/ath5k
drivers/net/wireless/ath5k/base.c
drivers/net/wireless/ath5k/pcu.c
but it doesn't seem it's one of those.
