This error is only thrown by run_connectivity_test in hwsim_utils.py.
Due to the way test_ap_vlan_wpa2_radius_mixed calls this, dev1group and
dev2group are False and dev1/ifname1 is the wpa_supplicant interface and
dev2 is the hostapd and ifname2 the hostapd managed bridge.
So the relevant code is like:

<code>
ev = dev2.wait_event(["DATA-TEST-RX"], timeout=timeout)
if ev is None:
  raise Exception("dev1->dev2 unicast data delivery failed")
if "DATA-TEST-RX {} {}".format(addr2, addr1) not in ev:
  raise Exception("Unexpected dev1->dev2 unicast data result")
</code>

So there is some DATA-TEST-RX event in dev2 (hostapd), but the mac
addresses do not match. The mac addresses used are explicitly given by
DATA_TEST_TX and are figured out from the wlan0/wlan3 interface (not the
vlan interface or bridge), so nothing should be findling with that.

Also, I cannot reproduce this issue using
example-hostapd/wpa_supplicant.conf.
