Code includes wmb() followed by writel(). writel() already has a
barrier on some architectures like arm64.
This ends up CPU observing two barriers back to back before executing
the register write.
Since code already has an explicit barrier call, changing code to
wmb()
writel_relaxed()
mmiowb()
for multi-arch support.

A control queue is a hardware interface which is used by the driver
to interact with other subsystems (like firmware, PHY, etc.). It is
implemented as a producer-consumer ring. More specifically, an
"admin queue" is a type of control queue used to interact with the
firmware.
This patch introduces data structures and functions to initialize
and teardown control/admin queues. Once the admin queue is initialized,
the driver uses it to get the firmware version.

After the qdisc lock was dropped in pfifo_fast we allow multiple
enqueue threads and dequeue threads to run in parallel. On the
enqueue side the skb bit ooo_okay is used to ensure all related
skbs are enqueued in-order. On the dequeue side though there is
no similar logic. What we observe is with fewer queues than CPUs
it is possible to re-order packets when two instances of
__qdisc_run() are running in parallel. Each thread will dequeue
a skb and then whichever thread calls the ndo op first will
be sent on the wire. This doesn't typically happen because
qdisc_run() is usually triggered by the same core that did the
enqueue. However, drivers will trigger __netif_schedule()
when queues are transitioning from stopped to awake using the
netif_tx_wake_* APIs. When this happens netif_schedule() calls
qdisc_run() on the same CPU that did the netif_tx_wake_* which
is usually done in the interrupt completion context. This CPU
is selected with the irq affinity which is unrelated to the
enqueue operations.
To resolve this we add a RUNNING bit to the qdisc to ensure
only a single dequeue per qdisc is running. Enqueue and dequeue
operations can still run in parallel and also on multi queue
NICs we can still have a dequeue in-flight per qdisc, which
is typically per CPU.

sh_eth: unify the SoC feature checks
Here's a set of 5 patches against DaveM's 'net-next.git' repo.
The Ether driver sometimes uses the bit fields in 'struct sh_eth_cpu_data'
to check which Ether registers exist in a certain SoC and sometimes it uses
sh_eth_is_{gether|rz_fast_ether}() which basically compares 2 pointers (1 of
them being constant) -- the latter is definitely not a strongest feature of
the RISC CPUs (be it SH or ARM), so I decided to get rid of this type of
the feature checks in favour of the bit fields (I've also made use of a
32-bit value and method pointer where appropriate)...
[1/5] sh_eth: add sh_eth_cpu_data::soft_reset() method
[2/5] sh_eth: add sh_eth_cpu_data::edtrr_trns value
[3/5] sh_eth: add sh_eth_cpu_data::xdfar_rw flag

GEther controllers have CERCR/CEECR instead of CNDCR on the others.
Currently we are calling sh_eth_is_gether() in order to check for this,

this case. Currently we are calling sh_eth_is_rz_fast_ether() in order
to check for this, but it would be simpler to check the new 'no_tx_cntrs'

sh_eth_get_edtrr_trns() returns the value to be written to EDTRR in order
to start TX DMA -- this value is different between the GEther-like and
the other controllers. We can replace this function (and thus get rid of
the calls to sh_eth_is_{gether|rz_fast_ether}() by it) with a new field
'edtrr_trns' in the 'struct sh_eth_cpu_data'.

sh_eth_reset() performs a software reset which is implemented in a
completely different way for the GEther-like controllers vs the other
controllers due to a different layout of EDMR (and other factors) --
it therefore makes sense to convert this function to a mandatory
sh_eth_cpu_data::soft_reset() method and thus get rid of the runtime
controller type check via sh_eth_is_{gether|rz_fast_ether}().

If a storage device handled by BFQ happens to be slower than 7.5 KB/s
for a certain amount of time (in the order of a second), then the
estimated peak rate of the device, maintained in BFQ, becomes equal to
0. The reason is the limited precision with which the rate is
represented (details on the range of representable values in the
comments introduced by this commit). This leads to a division-by-zero
error where the estimated peak rate is used as divisor. Such a type of
failure has been reported in [1].
This commit addresses this issue by:
1. Lower-bounding the estimated peak rate to 1
2. Adding and improving comments on the range of rates representable

Most of the generic data structures embedded in xfs_mount are
dynamically initialized immediately after mp is allocated. A few
fields are left out and initialized during the xfs_mountfs()
sequence, after mp has been attached to the superblock.
To clean this up and help prevent premature access of associated
fields, refactor xfs_mount allocation and all dependent init calls
into a new helper. This self-documents that all low level data
structures (i.e., locks, trees, etc.) should be initialized before
xfs_mount is attached to the superblock.

When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
(ieee80211_sta) delete will trigger the kernel panic.
This problem arise in AP + Mesh configuration, Where the current node AP VAP
and neighbor node mesh VAP MAC address are same. When the current mesh node
try to establish the mesh link with neighbor node, driver peer creation for
the neighbor mesh node fails due to duplication MAC address. Already the AP
VAP created with same MAC address.
It is caused by the following scenario steps.
Steps:
1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
fails to do the state change for a station from IEEE80211_STA_NOTEXIST
to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
called from ieee80211_add_station() to handle the new station
(neighbor mesh node) request from the wpa_supplicant.
2. Concurrently ath10k receive the sta_rc_update callback notification from
the mesh_neighbour_update() to handle the beacon frames of the above
neighbor mesh node. since its atomic callback, ath10k driver queue the
work (ath10k_sta_rc_update_wk) to handle rc update.
3. Due to driver sta_state callback fails (step 1), mac80211 free the station
object.
4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
the station object which is already deleted. so it will trigger kernel
panic.
Added the peer exist check in sta_rc_update callback before queue the work.

- Number of MSDUs dropped in the driver
- A-MPDU/A-MSDU subframe stats
- Number of MSDUS passed to mac80211
All stats other than A-MPDU stats are only for received data frames.
A-MPDU stats might have stats for management frames when monitor
interface is active where management frames are notified both in wmi
and HTT interfaces.
These per tid stats can be enabled with tid bitmask through a debugfs
like below
echo <tid_bitmask> > /sys/kernel/debug/ieee80211/phyX/ath10k/sta_tid_stats_mask
tid 16 (tid_bitmask 0x10000) is used for non-qos data/management frames
The stats are read from
/sys/kernel/debug/ieee80211/phyX/netdev\:wlanX/stations/<sta_mac>/dump_tid_stats
Sample output:
To enable rx stats for tid 0, 5 and 6,
echo 0x00000061 > /sys/kernel/debug/ieee80211/phy0/ath10k/sta_tid_stats_mask
cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan15/stations/8c\:fd\:f0\:0a\:8e\:df/dump_tid_stats
