cfg80211: add peer measurement with FTM initiator API
Add a new "peer measurement" API, that can be used to measure
certain things related to a peer. Right now, only implement
FTM (flight time measurement) over it, but the idea is that
it'll be extensible to also support measuring the necessary
things to calculate e.g. angle-of-arrival for WiGig.
The API is structured to have a generic list of peers and
channels to measure with/on, and then for each of those a
set of measurements (again, only FTM right now) to perform.
Results are sent to the requesting socket, including a final
complete message.
Closing the controlling netlink socket will abort a running
measurement.
v3:
- add a bit to report "final" for partial results
- remove list keeping etc. and just unicast out the results
to the requester (big code reduction ...)
- also send complete message unicast, and as a result
remove the multicast group
- separate out struct cfg80211_pmsr_ftm_request_peer
from struct cfg80211_pmsr_request_peer
- document timeout == 0 if no timeout
- disallow setting timeout nl80211 attribute to 0,
must not include attribute for no timeout
- make MAC address randomization optional
- change num bursts exponent default to 0 (1 burst, rather
rather than the old default of 15==don't care)
v4:
- clarify NL80211_ATTR_TIMEOUT documentation
v5:
- remove unnecessary nl80211 multicast/family changes
- remove partial results bit/flag, final is sufficient
- add max_bursts_exponent, max_ftms_per_burst to capability
- rename "frames per burst" -> "FTMs per burst"
v6:
- rename cfg80211_pmsr_free_wdev() to cfg80211_pmsr_wdev_down()
and call it in leave, so the device can't go down with any
pending measurements
v7:
- wording fixes (Lior)
- fix ftm.max_bursts_exponent to allow having the limit of 0 (Lior)
v8:
- copyright statements
- minor coding style fixes
- fix error path leak
