The radiotap and PPI specs don't call them type fields, and don't list
them as having type values, they call them flags fields and list the
individual bits.
Listing them as type fields is especially confusing with radiotap, as
you can have multiple fields giving *different* channel types, as per,
for example
https://ask.wireshark.org/questions/42888/multiple-channel-types-and-mcs-missing
where an 802.11ac packet has one "channel type" field claiming it's
802.11a and another one claiming it's 802.11n when it is, in fact,
*neither* 11a *nor* 11n.
If you want to know the channel type, look at the "802.11 radio
information" tree that comes before the 802.11 header tree; it gives a
reasonable summary of most of the radio metadata, giving the *correct*
channel type, and not showing any field multiple times. Look at the
radiotap or PPI or... tree only if either 1) you're debugging a driver
that creates those headers or 2) there's some data in the header that
*doesn't* show up in any form in the 802.11 radio information tree (in
which case the code for radio information probably needs to be changed
to show it).

Provide that information so that the "802.11 radio information" protocol
can indicate whether a packet was 802.11 legacy/11b/11a/11g/11n/11ac,
and possibly whether it's 2.4 GHz or 5 GHz 11n. (Sometimes the center
frequency might not be supplied, so the band information can be useful.)
Also, provide some 11ac information, now that we can distinguish between
11n and 11ac. Don't calculate the data rate from the MCS index unless
it's 11n; we don't yet have code to calculate it for 11ac.
For radiotap, only provide guard interval information for 11n and 11ac,
not for earlier standards.
Handle the 11ac flag in the Peek remote protocol.
For Peek tagged files, the "extension flags" are 11n/11ac flags, so we
don't have to check for the "MCS used" bit in order to decide that the
packet is 11n or 11ac or to decide whether to provide the "bandwidth" or
"short GI" information.

From 3GPP 23.003
The GSN Address is composed of the following elements:
1) The Address Type, which is a fixed length code (of 2 bits) identifying the type of address that is used in the
Address field.
2) The Address Length, which is a fixed length code (of 6 bits) identifying the length of the Address field.
3) The Address, which is a variable length field which contains either an IPv4 address or an IPv6 address.
Address Type 0 and Address Length 4 are used when Address is an IPv4 address.
Address Type 1 and Address Length 16 are used when Address is an IPv6 address.
The IP v4 address structure is defined in RFC 791 [14].
The IP v6 address structure is defined in RFC 2373 [15].
Currently the Wireshark decodes IPv6 addresses as IPv4
