Comment(by dsd):

 This is a malformed probe response.

 The final good tagged parameter is 00 03 a4 00 00
 00 = SSID tag
 03 = length 3
 a4 00 00 = the SSID (!?)

 Next tag is code 0x27, OFW doesn't seem to recognise but wireshark says
 this is a measurement report.
 The length is claimed to be 0xa4 (164) but then there are less than 164
 bytes following --> this is where OFW gets confused.

 Mitch says he's hardened this up a bit in the source. Which is good,
 because my wireshark session showed some even more corrupted probe
 responses at other times.
