* Add the command groups enum, and the iwm_phy_ops_subcmd_ids enum
  to if_iwmreg.h definitions.

a717dd3a7f [iwm] Very basic DTS thermal sensor support (prints temp as debug msg).
* Adds IWM_DEBUG_TEMP debug message type, for printing messages related
  to temperature sensors and thermal/TDP infos.

* The firmware regularly sends us DTS measurement notifications, so just
  print the temperature value as a debugging message.

(Adrian's addition):

* Eventually this can be used by the driver to limit transmit rate / power to
  try and do some thermal throttling.

82ba706cba [iwm] Use iwm_mvm_scan_stop_wait to properly abort scans.
* Add IWM_FLAG_SCAN_RUNNING to sc->sc_flags to track whether the firmware
  is currently running a scan, in order to decide wheter iwm_scan_end
  needs to abort a running scan.

* In iwm_scan_end, if the scan is still running, we now abort it, in order
  to keep the firmware scanning state in sync.

* Try to make things a bit simpler, by reacting on the
  IWM_SCAN_OFFLOAD_COMPLETE and IWM_SCAN_COMPLETE_UMAC notifications,
  instead of IWM_SCAN_ITERATION_COMPLETE and
  IWM_SCAN_ITERATION_COMPLETE_UMAC. This should be fine since we always
  only tell the firmware to do a single scan iteration anyway.

4623c73135 iwm: add missing 'Rx errors' counter incrementation. 2016-10-09 10:21:28 +00:00
Adrian Chadd
e97796e2b6 [net80211] extend the ieee80211_rx_stats struct to include more information.
There are a variety of more interesting RX statistics that we should
keep track of but we don't.  This is a starting point for adding more
information.

Specifically:

* now the RX rate information and some of the packet status is
  passed up;
* The 32 bit or 64 bit TSF is passed up;
* the PHY mode is passed up;
* the "I'm decap'ed AMSDU!" state is passed up;
* number of RX chains is bumped to 4.

This is all mostly a placeholder for getting the data into the RX status
before we pass it up to net80211 - unfortunately we don't yet enforce
that drivers provide it, nor do we pass the provided info back up the
stack so anyone can use the data.

We're going to need to use some of this data moving forward.
Notably, now that some hardware can do AMSDU decap for us (the intel iwm
driver can do it when we flip it on; the ath10k port I'm doing does
it for us) then we need to pass it up through the stack so the duplicate
RX sequence numbers and crypto/IV details don't cause the packet to
be dropped and/or counted against a replay counter.

It's also the beginning of being able to do more interesting node
accounting in net80211.  Specifically, once drivers start populating
per-packet rate information, AMPDU information, timestamps, etc,
we can start providing histograms of rate-versus-RSSI, account
for receive time spent per node and other such interesting things.

(Note: I'm also hoping to include ranging and RTT information for
future chipset support; and it's likely going to include it in
this kind of fashion.)

f6930bec33 net80211: ieee80211_ratectl*: switch to reusable KPI
Replace various void * / int argument combinations with common structures:
- ieee80211_ratectl_tx_status for *_tx_complete();
- ieee80211_ratectl_tx_stats for *_tx_update();

While here, improve amrr_tx_update() for a bit:
1. In case, if receiver is not known (typical for Ralink USB drivers),
refresh Tx rate for all nodes on the interface.
2. There was a misuse:
- otus(4) sends non-decreasing counters (as originally intended);
- but ural(4), rum(4) and run(4) are using 'read & clear' registers
to obtain statistics for some period of time (and those 'last period'
values are used as arguments for tx_update()). If arguments are not big
enough, they are just discarded after the next call.

Fix: move counting into *_tx_update()
(now otus(4) will zero out all node counters after every tx_update() call)

Tested with:
- Intel 3945BG (wpi(4)), STA mode.
- WUSB54GC (rum(4)), STA / HOSTAP mode.
- RTL8188EU (urtwn(4)), STA mode.

6f87599bdf [iwm] fix default antenna selection a bit; fix 5GHz rate control handling.
* Don't do the antenna switching when setting up the rate table - we don't
  take into account whether it's an active antenna or not (eg shared with BT.)
  I'll look into this a bit more later.

* The default antenna is still 1, I'll look into that a bit more later.
  (So no, this doesn't fix it for Larry who needs ANT_B to be active, not
  ANT_A.)

* My changes to the rate control setup used the wrong method for finding
  a suitable rate, which led to 1M CCK frames being queued for 11a operation.
  This is .. sub-optimal.  Change the rate control lookup path to use
  the global table instead of the per-node table, which won't be setup
  until the node rate table is setup (which happens way too late in this
  game.)
