5538409ba3 iwlwifi: pcie: support page dumping in wrt in gen2
In gen2, page dumping needs to be done in the trans
layer, as it is the one with access to the paging
pointers.

2ba57c8bf9 iwlwifi: mvm: remove wrt support of page dumps in gen2
In gen2, page dumping should be done in transport
layer, since the addresses needed for the paging
mechanism reside there.

====================
Another set of patches for -next:
 * API support for concurrent scheduled scan requests
 * API changes for roaming reporting
 * BSS max idle support in mac80211
 * API changes for TX status reporting in mac80211
 * API changes for RX rate reporting in mac80211
 * rewrite monitor logic to prepare for BPF filters
 * bugfix for rare devices without 2.4 GHz support
 * a bugfix for recent DFS changes
 * some further cleanups

The API changes are actually at a nice time, since it's
typically quiet just before the merge window, and trees
can be synchronized easily during it.

ca986ad9bc nl80211: allow multiple active scheduled scan requests
This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.

Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

Export two APIs that op mode will still use.
Adjust API of init_sbands to be independent of NVM file structure
so it can be used by op mode as well.

ced19f2696 iwlwifi: mvm: support station type API
Support change to ADD_STA API to support station types.
Each station is assigned its type.
This simplifies FW handling of the broadcast and multicast
stations:
* broadcast station is identified by its type and not the mac
  address.
* multicast queue is no longer treated differently. The opening
  and closing of it is done by referring to its station.
  There is no need to specify it in the MAC command.
* When disabling TX to all station driver can disable the traffic
  on multicast station, so FW doesn't have to do it.
Change is backward compatible.
Change the order of adding and removing the stations according to
FW requirements.

34e10860ae iwlwifi: mvm: remove references to queue_info in new TX path
Most of the fields aren't needed in new TX path.
Enlarging the struct to 512 queues will consume a lot of memory.
Remove all references to the struct in the new TX path.
Move mac80211 queue mapping outside, since it will be needed per
queue for TVQM mode.
Add warning in paths that shouldn't be hit.

06a1e85e66 iwlwifi: remove module loading failure message
When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes
when the opmode module cannot be loaded, due to completing
the completion before using drv->dev, which can then already
be freed.

Fix this by removing the (fairly useless) message. Moving the
completion later causes a deadlock instead, so that's not an
option.

53d515ec67 iwlwifi: don't leak memory on allocation failure
If we fail to allocate the small chunk of memory for the
pieces of the firmware file, we leak the whole firmware
image instead...

Since the allocation failure is really unlikely, just bail
out at that point instead.

Remove the error message at the label since we now (and
actually have been) use it for various reasons.

Support it by maintaining internal mapping between the actual number

Wifi mcc (mobile country code) update is forbidden while associated.
Currently, FW prevents these updates and the driver is unaware to
this logic. From now on, the FW sends every wifi mcc update to the
