very small boot loader is burned to the on-board flash. Boot loader
initializes hardware upon reset, and prepares for low power mode.
Boot loader reports MAC address and detects radio chip connected.

Driver loads firmware only when bringing up interface. All information
required to set up network interface, most important is MAC address,
reported by the boot loader

- wil6210.fw - firmware itself (compiled code + data)
- wil6210.board - board file (various board and radio dependent
  calibrations and parameters)

8bfae4f993 ath5k: fix spontaneus AR5312 freezes
Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.

The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.

This patch partially reverts the commit 1846ac3dbe ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().

I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.

Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

627613f8f0 ath10k: prevent setting wrong key idx for station
Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.

The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.

Used TX_USAGE flag to set default key for stations.

Added callback for setting unicast default idx which will be
invoked on every default key idx configuration.

QCA953x, since it is problematic on a few boards.
Instead, manual calibration will be done in the

e3f31175a3 ath9k: fix race condition in irq processing during hardware reset
To fix invalid hardware accesses, the commit 872b5d814f ("ath9k: do not
access hardware on IRQs during reset") made the irq handler ignore interrupts
emitted after queueing a hardware reset (which disables the IRQ). This left a
small time window for the IRQ to get re-enabled by the tasklet, which caused
IRQ storms.  Instead of returning IRQ_NONE when ATH_OP_HW_RESET is set, disable
the IRQ entirely for the duration of the reset.

b51f3beecf cfg80211: change bandwidth reporting to explicit field
For some reason, we made the bandwidth separate flags, which
is rather confusing - a single rate cannot have different
bandwidths at the same time.

Change this to no longer be flags but use a separate field
for the bandwidth ('bw') instead.

While at it, add support for 5 and 10 MHz rates - these are
reported as regular legacy rates with their real bitrate,
but tagged as 5/10 now to make it easier to distinguish them.

In the nl80211 API, the flags are preserved, but the code
now can also clearly only set a single one of the flags.

4447d815fd ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries
Use the helper to get rid of the file operations per debugfs file. The
device driver data contains struct ieee80211_hw pointer and the
struct ath9k_softc pointer is assigned to ieee80211_hw::priv so it can
be accessed in the seq_file read operation.

bd33273b65 wil6210: relax spinlocks in rx reorder
In the Rx reorder mechanism, nothing is done in the interrupt
context, so there is no need to use 'irq' flavors of spinlock.
Rx done in NAPI context (tasklet), other manipulations - in the
thread context.

Having interrupts enabled makes it better for the OS in general.
Besides, if enslaved under bonding, bridge or team driver, Rx
won't work with interrupts disabled.

78366f69be wil6210: add advanced interrupt moderation
Add advanced interrupt moderation support available since "Sparrow B0".
Legacy interrupt moderation used only one counter to moderate tx, rx,
and misc interrupts.
Advanced interrupt moderation bypasses misc, and handles separately tx
and rx interrupts. In addition it has two timers for each interrupt type.
Max burst duration timer which defines how long to postpone interrupt after
first event (receive event for rx and tx complete event for tx), and
interframe timeout which defines how to determine the end of the burst and
issue interrupt even if the first timer still pending.
Capabilities flags in wil_priv is set on initialization according to
HW. The rest of the code checks for advanced interrupt capability bit
in capabilities flags field.
Debugfs is split accordingly: "legacy" interrupt moderation remains
unchanged, new debugs files added for advanced interrupt moderation
support.
Module params are aligned to support advanced interrupt moderation
(tx & rx). When not available (for legacy interrupt moderation) will
use only rx configuration; Tx configuration will be ignored in this
case.
