There is an ongoing work on cleaning MIPS's nvram support so it could be
re-used on other platforms (bcm53xx to say precisely).
This will require a bit of extra logic in bcma this patch implements.

Unify all the functions that handle the per-interface broadcast
station and make them have mvm and vif parameters. While at it,
add a new function to allocate the broadcast station instead of
open-coding it, and make the combined alloc+send and free+send
functions use the alloc/free & send functions.

There are a few places that can call the function
iwl_mvm_mac_get_queues_mask() instead of open-coding the
equivalent, so do that. This requires changing it to return
the multicast queue as part of the bitmap, which broke GO
mode because including it in the broadcast station queues
seems to confuse the firmware, so work around that.
Also, the API defines that the CAB queue shouldn't be
included in the TFD queue mask, adjust the comment
accordingly (not a bug).

The queue handling is a bit unclear - we have an array for
stop_count[IWL_MAX_HW_QUEUES] but indices really are the
mac80211 queue numbers. Change the array to be only of the
right size for mac80211 queues (IEEE80211_MAX_QUEUES) and
rename it to be clearer.
While at it, also remove the unused transport queue stop
bitmap in mvm.

The firmware would like to have a MAC context (unassoc)
before the AP station is removed (we do this) but would
like to keep the BSSID until after it is removed, so we
need to send two commands - one with the BSSID before
and one without the BSSID after.
In order to do this, we need to store the BSSID as it
will have been cleared by mac80211 by the time we get
notified of the disassociation. Also pass it around as
an override to the various functions needing it, and
keep taking it from the mac80211 data otherwise. This
avoids having to keep track of the BSSID in all modes.

Currently the firmware is handling this, but that is wrong as it then
needs to assume a certain command queue, therefore this should be in
the driver; add it here so it can be removed from the firmware in the

Currently a valid sta_id is assumed to mean that the queue is
meant to also be aggregated, but that assumption will not be

only in the inline wrapper.

Configuring the hw scheduler during queue enablement is done by
writing the appropriate values to the scheduler peripherals, and
it is essentially the same for all buses.
Whenever writing is done via the standard iwl_write_prph, we can
avoid duplicating the code for each bus. Those operations are
queue deactivation, RA/TID mapping, chain-building settings,
enabling/disabling aggregations and activating/deactivating the
TX FIFOs.
Consolidate this code using static inlines in a new header file.

when a channel switch is happening. Add a boolean to mvmvif that
