Arrays of dictionaries are quite common, and for basic
types this API makes things much more convenient by
putting all the enter/append/leave calls in one place.

New subject: [PATCH v3 2/8] netdev: add netdev_get_station/current_station
This adds a generalized API for GET_STATION. This API handles
calling and parsing the results into a new structure,
netdev_station_info. This results structure will hold any
data needed by consumers of netdev_get_station. A helper API
(netdev_get_current_station) was added as a convenience which
automatically passes handshake->aa as the MAC.
For now only the RSSI is parsed as this is already being
done for RSSI polling/events. Looking further more info will
be added such as rx/tx rates and estimated throughput.

So looking at how the kernel reports MCS info, I'm not sure this is entirely
right. It seems the kernel can report the VHT MCS index instead of the regular
one (or HE one). So the question is, do we want to report the VHT/non-VHT MCS
indexes separately or report either of them in the mcs index variable. If the
latter, then we'd need to add some sort of 'tech attribute' to distinguish
what
MCS is being meant. i.e. is it a VHT (802.11ac) MCS index or not.
We should also probably report the bandwidth (5/10/20/40/80/160, etc)

New subject: [PATCH v3 8/8] doc: update diagnostics with [optional] tags
Some elements, though unlikely, are not required to be included
with the GET_STATION call that GetDiagnostics relies on. mac80211
based drivers include most of these, but other drivers may not.
To be on the safe side all properties except ConnectedBss are now
optional and may not be included.

Arrays of dictionaries are quite common, and for basic
