Specifically, it has to report center frequency, secondary center
frequency (for 80+80) and BW.
Introduce channel definition structure to qlink and modify channel
change event processing function accordingly.

This will allow to use qlink channel width values to specify BW setting
corresponding to enum nl80211_chan_width.
Current user is converted to apply BIT() macro manually to each individual
qlink_channel_width enumeration value.

Don't populate the read-only const array tos_to_ac on the stack,
instead make it static. Makes the object code smaller by 250 bytes:
Before:
text data bss dec hex filename

After:

I assume that a blank efuse comes with all ones, thus I did not bother
recognizing other possible junk values. This matches 100% of dongles
I've seen (a single Gembird 8192eu).

wcn3620 can only operate on 2.4GHz band due to RF limitation.
If wcn36xx digital block is associated with an external IRIS
RF module, retrieve the id and disable 5GHz band in case of
wcn3620 id.

Lockdep warns us that sc_pm_lock and cc_lock can cause a deadlock when
cc_lock is acquired by itself with interrupts enabled. Disable irqs
whenever taking cc_lock to avoid this.
[ 19.094524] kworker/u2:0/5 just changed the state of lock:
[ 19.094578] (&(&sc->sc_pm_lock)->rlock){-.-...}, at: [<f836c00e>] ath_isr+0x15e/0x200 [ath9k]
[ 19.094674] but this lock took another, HARDIRQ-unsafe lock in the past:
[ 19.094731] (&(&common->cc_lock)->rlock){+.-...}
[ 19.094741]
and interrupts could create inverse lock ordering between them.

The mac80211_hwsim doesn't offer a way to disable the debugging output.
Unfortunately, it's pretty chatty, dumping a lot of stuff into the message
buffer.
This patch changes it to use dyndbg for controlling the debug output.
It's disabled by default, but can be enabled by a module parameter (1),
at runtime (2) or persisted in modprobe.conf (3).
(1) modprobe mac80211_hwsim dyndbg=+p
(2) echo "module mac80211_hwsim +p" >/sys/kernel/debug/dynamic_debug/control
(3) echo "options mac80211_hwsim dyndbg=+p" >>/etc/modprobe.d/my.conf

Application will keep track of whether MAC address randomization
is enabled or not during scan. But at present driver is storing
'random_mac' in mwifiex_private which implies even after scan is
done driver has some reference to the earlier 'scan request'. To
avoid this, make use of 'mac_addr' variable in 'scan_request' to
store 'random_mac'. This structure will be freed by cfg80211 once
scan is done.

In routine rtl92ee_set_fw_rsvdpagepkt(), the driver allocates an skb, but
never calls rtl_cmd_send_packet(), which will free the buffer. All other
rtlwifi drivers perform this operation correctly.
This problem has been in the driver since it was included in the kernel.
Fortunately, each firmware load only leaks 4 buffers, which likely
explains why it has not previously been detected.

The condition to check if reorder buffer ran out of
space is faulty, as it takes into account only the
NSSN.
In case the head SN was too far behind the reorder
buffer should move forward, regardless of the NSSN
status.
This caused the driver to release packets out of order
in some scenarios.

We were ignoring the FIF_ALLMULTI flag when setting the multicast
addresses with MCAST_FILTER_CMD. Check if this flag is set and enable
pass_all accordingly. We also need to set the count to 0 if pass_all
is enable so we don't pass addresses to the firmware when not needed
(as doing so causes an assert).
