If the virtual monitor interface is requested
by the driver, it should also be iterated over
when the driver wants to iterate all active
interfaces.
To allow that protect it with the iflist_mtx.

To call cfg80211_get_chan_state() we need to lock
the wdev, so we need to lock the wdev_iter mutex
in cfg80211_can_use_iftype_chan(). This needs to
use nested locking for lockdep.
Also, cfg80211_get_chan_state() doesn't actually
use the rdev, so remove that completely including
the lock assertion that isn't needed.

When sample_idx is set to a value other than -1 it activates
the IEEE80211_TX_CTL_RATE_CTRL_PROBE flag which disables
frame aggregation. To allow frame aggregation during fixed
rate it is necessary to set max_tp_rate, max_tp_rate2 and
max_prob_rate instead of sample_idx.

When drop_unencrypted is enabled and MFP is disabled,
non-robust management frames for not-yet associated STA are dropped.
This isn't visible as many management frames sent from the kernel
have TX_INTFL_DONT_ENCRYPT set and management frames injected
from a monitor vif have TX_CTL_INJECTED so aren't dropped.
But management frames sent from userspace via NL80211_CMD_FRAME
do not have this flag set, so are dropped.
This patch make it always accept non-robust management frames.

Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
bss_conf.last_tsf value. By itself though that value is
completely worthless since it may be ancient. What really
is needed is synchronisation between some device time and
the TSF.
To clarify this, rename bss_conf.last_tsf to sync_tsf and
add sync_device_ts which is obtained from rx_status which
gets a new field device_timestamp for this purpose. This
is intentionally not using the mactime field since that
is used for other things and in IBSS is expected to sync
with the IBSS's TSF which isn't necessarily true for the
device timestamp.
Also, since we have the information and it's useful even
before the connection has been established, give all the
timing details to the driver before authenticating.

Scan receive is rather inefficient when there are
multiple virtual interfaces. We iterate all of the
virtual interfaces and then notify cfg80211 about
each beacon many times.
Redesign scan RX to happen before everything else.
Then we can also get rid of IEEE80211_RX_IN_SCAN
since we don't have to accept frames into the RX
handlers for scanning or scheduled scanning any
more. Overall, this simplifies the code.

Instead of tracking whether or not we're in a
scheduled scan, track the virtual interface

usable from RX to check the MAC address.

Making the scan_sdata pointer usable with RCU makes
it possible to dereference it in the RX path to see
if a received frame actually matches the interface
that is scanning. This is just preparations, making
the pointer __rcu.

The function building probe-request IEs does not validate the band is
supported before dereferencing it. This can result in a panic when
all bands are traversed, as done during sched-scan start.
Warn when this happens and return an empty probe request. Also fix
sched-scan to not waste memory on unsupported bands.

This patch adds an alternative tx status path
for BlockAck Requests as the hardware doesn't
recognize that a BlockAck Requests is usually
acked with a BlockAck and not a legacy ACK.
Without this patch, the stack would constantly
resent old and stale BARs. So, depending on the
receiver stack, this could lead to:
- "stuck" ba sessions and package loss, as the
stale BAR would reset the sequence each time.
- lots of reorder releases.

Instead of checking if there is a PCIe core on the bus, better check if
hosttype is PCIe.
In the original submission to staging PCIE() checked, if the bustype is
PCI and the buscore is a PCIe core. Now we assume that all cores bcma
supports are PCIe based, so we just have to check if the bustype is PCI.
The old code bcmsmac currently uses searches for a PCIe core on the bus
and if there is one assumes that this is the buscore, which is wrong.
Some SoCs have a PCIe core operating in host mode and this is not the
bus core. The old code also caused a null pointer in
ai_get_buscoretype() and ai_get_buscorerev() if buscore was not set
because there was no PCIe core on the bus.
