Hi,
Here's the last batch of patches intended for 4.17. I'm also
including the 5 patches I sent out last year and were still pending,
since they were rebased and some have changed slightly.
The old series contains these:
* Fix a UBSAN warning;
* Improvement in the net-stack/driver log syncing
* An RCU lock fix in the new rate-scaling code;
* Small cleanups;
The new series of 9 patches contains:
* Support for new PCI IDs for the 9000 family;
* Support for a new API version;
* Initial work for supporting the new ETSI rules;
* Support for advanced dwell in scanning;
* Support for OCE in scanning;
* Some debugging improvements;
* Other small improvements here and there.
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Cheers,
Luca.

Normally, this triggers don't cause the FW to be restarted, but in some cases that may be desired, so we recover from the problem. To support this, add a flag that indicates that the FW should be restarted when the trigger fires.

Currently iwlmvm indicates that the MAC is associated only after hearing a beacon from the AP. In case a deauthentication frame is sent before the MAC is associated, the frame might not be sent as the corresponding binding is not scheduled. To handle such cases, set IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP in the HW flags, requesting mac80211 to call the mgd_prepare_tx() callback before transmitting a deauthentication frame if associated but no beacon was heard from the AP. In addition, do not warn in iwl_mvm_mac_mgd_prepare_tx() when already associated as now the callback can be called also when associated.

This costs space, and requires to check each separately when determining low latency. Since we have another cause incoming, convert it to an enum. While at it, move the retrieval of the prev value and the assignment of the new value to be inside iwl_mvm_update_low_latency and save the need for each caller to do it separately.
