Yes - it came up with the Wireshark bug in question.

Yes - there's a macro in Wireshark to test whether a frequency is in the 11ad range; it was testing for frequencies between 57 and 66 GHz.  I changed the code to use that.

I also changed it to test for 57 to 71 GHz; apparently, some regulatory domains have added (US) or may add (Canada, EU) more frequencies to the range allowed.
