The wireshark shipped in Red Hat Enterprise Linux 6 and 7 do not have the dot11crypt traffic recognition functionality.

$ tshark -Vxr clusterfuzz-testcase-minimized-fuzzshark_ip_proto-udp-5122206420959232.pcap
tshark: The file "clusterfuzz-testcase-minimized-fuzzshark_ip_proto-udp-5122206420959232.pcap" contains record data that TShark doesn't support.
(pcap: network type 252 unknown or unsupported)
