         and just stick the payload into an 802.11 frame.  I've seen
         captures that show frames of that sort.

         We also handle some odd form of encapsulation in which a
         complete Ethernet frame is encapsulated within an 802.11
         data frame, with no 802.2 header.  This has been seen
         from some hardware.

         On top of that, at least at some point it appeared that
         the OLPC XO sent out frames with two bytes of 0 between
         the "end" of the 802.11 header and the beginning of
         the payload.

         So, if the packet doesn't start with 0xaa 0xaa:

           we first use the same scheme that linux-wlan-ng does to detect
           those encapsulated Ethernet frames, namely looking to see whether
           the frame either starts with 6 octets that match the destination
           address from the 802.11 header or has 6 octets that match the
           source address from the 802.11 header following the first 6 octets,
           and, if so, treat it as an encapsulated Ethernet frame;

           otherwise, we use the same scheme that we use in the Ethernet
           dissector to recognize Netware 802.3 frames, namely checking
           whether the packet starts with 0xff 0xff and, if so, treat it
           as an encapsulated IPX frame, and then check whether the
           packet starts with 0x00 0x00 and, if so, treat it as an OLPC

         *       with a value of HT_GF, HT_MF, or VHT for the FORMAT parameter

  /*
   * XXX - the 802.11 specs aren't particularly clear on how the SSID
   * is to be interpreted.
   *
   * IEEE Std 802.11-1999, section 7.3.2.2 "Service Set Identity (SSID)
   * element" says just
   *
   *    The length of the SSID information field is between 0 and 32
   *    octets. A 0 length information field indicates the broadcast SSID.
   *
   * with no indication that those octets encode a string.
   *
   * IEEE Std 802.11-2012, section 8.4.2.2 "SSID element", says that *but*
   * says after it
   *
   *    When the UTF-8 SSID subfield of the Extended Capabilities element
   *    is equal to 1 in the frame that includes the SSID element, the
   *    SSID is interpreted using UTF-8 encoding.
   *
   *    NOTE -- This is true for Beacon and Probe Response frames when the
   *    MLME-START.request primitive was issued with the SSIDEncoding
   *    parameter equal to UTF-8.
   *
   * and the SSIDEncoding parameter can either be UNSPECIFIED or UTF-8.
   *
   * IEEE Std 802.11-2020, section 9.4.2.2 "SSID element" changes the
   * wording to:
   *
   *    When the UTF-8 SSID subfield of the Extended Capabilities element is
   *    equal to 1 in the frame that includes the SSID element, or the Extended
   *    Capabilities of the source of the SSID information is known to include
   *    the UTF-8 SSID capability based on a previously received Extended
   *    Capabilities element, the SSID is a sequence of UTF-8 encoded code
   *    points. Otherwise, the character encoding of the octets in this SSID
   *    element is unspecified.
   *
   *    NOTE—If the SSID is a sequence of UTF-8 encoded code points, a
   *    terminating null might or might not be present.
   *
   * So I *guess* that means that, if the UTF-8 SSID subfield isn't
   * equal to 1, the SSID is, in theory, just a bunch of octets, but
   * in practice, *probably* UTF-8 as that's the typical convention,
   * and, if it is equal to 1, it's a possibly null-terminated UTF-8
   * string.  (Of course, a host can put anything there it wants to,
   * so we shouldn't just assume that it's *valid* ASCII or *valid* UTF-8.)
   *
   * So we really should extract it as an array of ssid_len bytes,
   * pass those bytes to Dot11DecryptSetLastSSID(), and:
   *
   *    If the UTF-8 SSID subfield isn't set to 1, put the SSID in
   *    a FT_BYTES as BASE_SHOW_UTF_8_PRINTABLE;
   *
   *    If the UTF-8 SSID subfield is set to 1, put it in as an
   *    ENC_UTF_8 string;
   *
   * XXX: Note that the Extended Capabilities tagged parameter is specified
   * to come *after* the SSID parameter (and "Fields and elements appear
   * in the specified, relative order" per 9.3.3.1 of IEEE 802.11 2020),
   * isn't sent with Response frames, and isn't guaranteed to appear with
   * Request frames (if none of the bits would be set, then it isn't
   * mandatory). We could store the bit if it appears in the conversation
   * data, which would handle Response frames and subsequent passes, but
   * for the first pass we don't know the value of the subfield until later.
   * We could store the proto_item with the ssid and add the string version
   * later, or add the string always as a hidden item and make it visible
   * later, or something else.
   *
   * Addendum: 802.11 2012 points out that a Zero-length SSID means
   * the Wildcard SSID. Make it so. From 8.4.2.2 of 802.11 2012:
   *
   * "The length of the SSID field is between 0 and 32 octets. A SSID
   *  field of length 0 is used within Probe Request management frames to
   *  indicate the wildcard SSID. The wildcard SSID is also used in
   *  Beacon and Probe Response frames transmitted by mesh STAs."
   *
   * Also, we have to return a non-zero value here to prevent an ugly
   * undissected field warning. Since this code is only called from
   * one place and is used in call to dissector_try_uint_new, it is
   * OK to do so.

        /* I guess some bridges take Netware Ethernet_802_3 frames,
           which are 802.3 frames (with a length field rather than
           a type field, but with no 802.2 header in the payload),
           and just stick the payload into an 802.11 frame.  I've seen
           captures that show frames of that sort.

           We also handle some odd form of encapsulation in which a
           complete Ethernet frame is encapsulated within an 802.11
           data frame, with no 802.2 header.  This has been seen
           from some hardware.

           On top of that, at least at some point it appeared that
           the OLPC XO sent out frames with two bytes of 0 between
           the "end" of the 802.11 header and the beginning of
           the payload. Something similar has also been observed
           with Atheros chipsets. There the sequence control field
           seems repeated.

           And, on top of *that*, IEEE Std 802.11-2018 section
           5.1.4 "MSDU format" says:

             Logical Link Control (LLC) sublayer entities use the MAC
             sublayer service to exchange PDUs with peer LLC sublayer
             entities. These PDUs are termed MAC sublayer SDUs (MSDUs)
             when sent to the MAC sublayer. There are two LLC sublayer
             protocols used (see IEEE Std 802-2014); LLC Protocol
             Discrimination (LPD) (see ISO/IEC 8802-2:1998) and EtherType
             Protocol Discrimination (EPD) (see IEEE Std 802.3-2012).
             LPD is used for transmission of all IEEE 802.11 MSDUs with
             the exception of the 5.9 GHz bands where EPD is used
             (see E.2.3 and E.2.4).

           and IEEE Std 1609.3-2016, section 5.2 "Logical link control",
           subsection 5.2.1 "General", says:

             A Networking Services implementation shall use EPD in the
             LLC sublayer as described in IEEE Std 802, using an EtherType
             in the LLC sublayer header Type9 field (see Figure 5 and
             Figure 28). The LLC sublayer header consists solely of a
             2-octet field that contains an EtherType that identifies
             the higher layer protocol.

           and ISO 21215, second edition, 2018-06, "Intelligent transport
           systems -- Localized communications -- ITS-M5", section 6.3
           "Logical link control sub-layer" says:

             IEEE Std 802.11TM-2016 does not specify a logical link control
             sub-layer protocol. Related functionality is part of the
             communication adaptation sub-layer specified in 6.4.

             The Length/Type field specified in IEEE 802.3-2015 contains
             a 2-octet unsigned Integer number. Dependent on the value,
             the field provides either length information or EtherType
             information. If the value contained in this field is equal
             to or larger than 1 536 = 0x06.00, the field contains an
             EtherType address. Ethertype addresses are assigned by the
             IEEE Registration Authority, and are used to identify the
             protocol employed directly above the ITS-S access layer.
             This method of addressing is named "EtherType Protocol
             Discrimination" (EPD). An ITS-M5 CI shall support EPD
             specified in IEEE Std 802.

                 ...

             NOTE 2    EPD replaces LLC Protocol Discrimination (LPD).
             ETSI ITS-G5 is the only known ITS access technology still
             using LPD.

             Different to the information in IEEE Std 802.11-2016, 5.1.4,
             EPD is applicable in all frequency bands as long as
             dot11OCBActivated is set to true, i.e. activating the operation
             mode "outside the context of a BSS" (OCB).

           meaning that a packet might just begin with an Ethertype.

           So, if the packet doesn't start with 0xaa 0xaa:

             we first use the same scheme that linux-wlan-ng does to detect
             those encapsulated Ethernet frames, namely looking to see whether
             the frame either starts with 6 octets that match the destination
             address from the 802.11 header or has 6 octets that match the
             source address from the 802.11 header following the first 6 octets,
             and, if so, treat it as an encapsulated Ethernet frame;

             otherwise, we use the same scheme that we use in the Ethernet
             dissector to recognize Netware 802.3 frames, namely checking
             whether the packet starts with 0xff 0xff and, if so, treat it
             as an encapsulated IPX frame;

             otherwise, we check whether the packet starts with 0x00 0x00
             or with a copy of the sequence control field and, if so, treat
             those two octets as mysterious extra stuff preceding the
             payload (possibly OLPC stuff, possibly Ruckus Wireless stuff,
             possibly Atheros stuff), and treat what follows as a frame
             using LPD;

             otherwise, we check whether the first two octets, treated
             as an Ethertype, has a dissector and, if so, treat this as
             a frame using EPD;

             otherwise, we treat this as a frame using LPD. */
