The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

Use the ENABLE_RX command for channel switching when no interface is present
(monitor mode only).
The advantage of ENABLE_RX is that it leaves the tx data path disabled in
firmware, whereas the usual JOIN command seems to transmit some frames at
firmware level.

With a dissasociated card I often encoutered very long scan delays.

My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.

Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

The destructor for net devices was set to free_netdev() to get rid
of it and the private data. The private data refers to a brcmf_if
instance, but indirectly it also refers to brcmf_cfg80211_vif which
holds the wdev. This is freed as well by using a new custom destructor
called brcmf_cfg80211_free_netdev().

Upon unload of the brcmfmac driver it gave a kernel warning because
cfg80211 still believed to be connected to an AP. The brcmfmac had
already transitioned to disconnected state during unload. This patch
adds informing cfg80211 about this transition. This will get rid of
warning from cfg80211 seen upon module unload:
