I'm trying to write a simple Lua dissector for VMware's Beacon protocol (ethertype 0x8922). For now I have:

local proto = Proto('vbeacon', 'vbeacon')

function proto.dissector(tvbuf, pinfo, tree)
    pinfo.cols.protocol = proto.name

    tree:add(proto, tvbuf(), 'Beacon')
end

DissectorTable.get('ethertype'):add(0x8922, proto)

In Wireshark the Beacon protocol is indeed recognized but Ethernet type is still Unknown. How can I update this Ethernet type?

Also note that these are not just used for Beacons, as per the description in the IEEE ether type filing.

This name resolution is build into Wireshark itself, there's no API for that.
