There are some races in the hardware that can possibly lead to
a bus lockup later during a restart when we manage to kill the
firmware at a bad time (while it's accessing the bus).
To work around this, add support for a new handshake between
firmware and driver to ensure that the firmware is in a well-
known state before we kill it.

When we get a channel switch with a very long quiet period, we schedule
a work to disconnect after a while. This work runs in background. In the
meanwhile, we keep getting beacons and sending FW modify command for each.
This has a potential race, where we modify the CSA after we aborted it.
Protect the flow by setting csa_failed to true in case we abort, and check
it before sending the modify command.
This required a modification to the way we treat csa_failed in
iwl_mvm_post_channel_switch:
1. The variable isn't being reset anymore, so we can still look at it in
iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when
starting a new CSA.
2. There is no more early return in case of csa_failed. This is fine,
since before this patch csa_failed was set only for GO, and for GO the
function is only resetting the power settings, which we want to restore
even in case of failure.

The argument type to iwl_mvm_notify_rx_queue() is currently just
a u8 *, but that's misleading because we actually need the inner
data to be of type struct iwl_mvm_internal_rxq_notif, because we
interpret it when we get it back from the device (to check the
sync bool and possibly the cookie.)
Therefore, clear up any potential confusion and require that the
data passed is of type struct iwl_mvm_internal_rxq_notif *.
Also, while at it, rename the "count" to "notif_size" as "count"
doesn't really clearly say what it's counting.

When adding support for version 3 of the GEO_TX_POWER_LIMIT command,
the table argument of iwl_sar_geo_init was changed from a pointer a 1d
array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d
array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a
struct containing 2 copies of iwl_per_chain_offset).
So even for version 2 where the second dimension is of length 2, which
means that the underlying memory layout of the array didn't change, this
requires a small change in the way we loop over it, and this was missed.
Additionally, for the case of version 3 where the second dimension is now
3, in order to fill the first two elements of each row correctly (lb and
hb), iwl_sar_geo_init must get the true number of bands supported.
But because we don't yet store any values for the 3rd (uhb) band, skip
that band.

ADD_STA_CMD_API_S ver 12 was added in order to properly support
auxiliary activities in CDB NICs. In the new version we don't need
to allocate an aux station at initialization, instead we add an
aux station only when an auxiliary activity that requires a dedicated Tx
queue is needed. For now the only case we need this kind of activity is
when using hot spot 2.0

As part of changes made to properly support auxiliary activities in CDB
NICs, an aux sta will be added when using hot spot 2.0 and will need
to be removed when roc flow is done.
In order to do so, prepare the roc_done_wk to work synchronously as the
rm_aux_sta is a SYNC command.
Since now all of th iwl_mvm_flush_sta function are using it sync,
removed the flag argument from the function.

The FW relies on the re-enablement of the TX in order to know
it can exit quiet mode. Currently in case of CSA with quiet mode,
the quiet mode is never cancelled, resulting in a complete traffic
hang.

If we have only a single RX queue, such as when MSI-X is not
available, we should not send the RFH_QUEUEU_CONFIG_CMD, because our
only queue is the same as the command queue and will be configured as
part of the context info. Our code was actually trying to send the
command with 0 queues, which caused UMAC assert 0x1D04.
Fix that by not sending the command when we have a single queue.
