Well, *if* there's useful radio information for 802.11ad that isn't provided by 
the MCS or VHT fields, perhaps there should be a DMG field, containing the 
radio information for 802.11ad, and 11ad captures should have that field rather 
than MCS or VHT.

Note that MCS and VHT both include certain fields, so presumably the idea is 
that an 11ac packet doesn't need both MCS *and* VHT fields.  If there's an DMG 
field that includes all radio information useful for 11ad, an 11ad capture 
would only need a DMG field, not an MCS or VHT field, and, for radiotap 
captures, a packet containing a DMG field could be treated as being an 11ad 
packet.  (Wireshark should probably warn if a packet contains more than one of 
MCS, VHT, or DMG.)

Note that the A-MPDU information has a separate field, which could be used in 
11n, 11ac, or 11ad frames.
