hostap in master mode and firmware 1.6.3

First of all I think that you should use PRI 1.1.1 together with STA 1.6.3.
But still, it doesn't seem to work in HostAP mode. No stations can
associate. I have verified with a spectrum analyzer that some kind of beacon
is being sent periodically, and the transmitted frequency responds when I
change channel with iwconfig. I suppose I should be able to capture the
frames by putting another card in monitor mode, but I actually don't know
exactly how to. Any hints? This is dmesg output from AP side:

wlan0: RX status=0x0000 (port=0, type=0, fcserr=0) silence=10 signal=43
rxflow=0; jiffies=97746
   FC=0x0080 (type=0:8) dur=0x0000 seq=0xb200 data_len=40
   A1=ff:ff:ff:ff:ff:ff A2=00:60:b3:6f:8b:56 A3=00:60:b3:6f:8b:56
   dst=ff:ff:ff:ff:ff:ff src=00:50:ba:e7:75:67 len=40
wlan0: prism2_rx: dropped non-data frame (type=0x00, subtype=0x08)
wlan0: RX status=0x0000 (port=0, type=0, fcserr=0) silence=14 signal=21
rxflow=0; jiffies=97747
   FC=0x0080 (type=0:8) dur=0x0000 seq=0xb850 data_len=37
   A1=ff:ff:ff:ff:ff:ff A2=00:05:4e:81:04:6a A3=00:05:4e:81:04:6a
   dst=ff:ff:ff:ff:ff:ff src=00:02:2d:27:4c:26 len=37
wlan0: prism2_rx: dropped non-data frame (type=0x00, subtype=0x08)
wlan0: RX status=0x0000 (port=0, type=0, fcserr=0) silence=12 signal=26
rxflow=0; jiffies=97748
   FC=0x0080 (type=0:8) dur=0x0000 seq=0x94b0 data_len=35
   A1=ff:ff:ff:ff:ff:ff A2=00:05:4e:81:02:a9 A3=00:05:4e:81:02:a9
   dst=48:05:c2:a1:57:3a src=b0:46:9f:f6:b1:86 len=35

Funny thing is that none of these MAC-addresses seem familiar to me. Exactly
what should these different address fields include?

BTW, new features in STA 1.6.3 seems to be RIDs for Enhanced Security, i.e.
hiding SSID in beacon and block responces to "ANY"-clients. "Frames to
stations in promiscous mode will now be ACKed", but I havn't verified that
yet. Otherwise it's mostly PS stuff.
