Why are my Wireshark Neighbor Report filters broken?

Just a short post to inform people that Wireshark have deprecated the filter ‘wlan.rm’ (which I presume stood for Radio Measurement) and moved the subfilters into ‘wlan.fixed’. This happened in Wireshark version 3.2.10.

For Neighbor Report Requests this is the change:
Old: wlan.rm.action_code == 4
New: wlan.fixed.action_code == 4

For Neighbor Report Responses this is the change:
Old: wlan.rm.action_code == 5
New: wlan.fixed.action_code == 5
