Section 4.5.9 of the datasheet says that the total size of all packet
buffers combined (TxPB 0 + 1 + 2 + 3 + RxPB + BMC2OS + OS2BMC) must not
exceed 60KB. Today we are configuring a total of 62KB, so reduce the
RxPB from 32KB to 30KB in order to respect that.
The choice of changing RxPBSIZE here is mainly because it seems more
correct to give more priority to the transmit packet buffers over the
receiver ones when running in Qav mode. Also, the BMC2OS and OS2BMC
sizes are already too short.

This change is based off of the work and suggestion of Jan Jablonsky
<jan.jablonsky@thalesgroup.com>.
The Watchdog workqueue in igb driver is scheduled every 2s for each
network interface. That includes updating a statistics protected by
spinlock. Function igb_update_stats in this case will be protected
against preemption. According to number of a statistics registers
(cca 60), processing this function might cause additional cpu load
on CPU0.
In case of statistics spinlock may be replaced with mutex, which
reduce latency on CPU0.

Add wmi configuration cmd to configure base band(BB) power amplifier(PA)
off timing values in hardware. The default PA off timings were fine tuned
to make proper DFS radar detection in QCA reference design. If ODM uses
different PA in their design, then the same default PA off timing values
cannot be used, it requires different settling time to detect radar pulses
very sooner and avoid radar detection problems. In that case it provides
provision to select proper PA off timing values based on the PA hardware used.
The PA component is part of FEM hardware and new device tree entry
"ext-fem-name" is used to indentify the FEM hardware. And this wmi configuration
cmd is enabled via wmi service flag "WMI_SERVICE_BB_TIMING_CONFIG_SUPPORT".
Other way is to apply these values through calibration data, but recalibration
of all boards out there might not be feasible.
This change tested on firmware ver 10.2.4-1.0-00042 in QCA988X chipset.

There was a race condition in SMP that an ath10k_peer was created but its
member sta was null. Following are procedures of ath10k_peer creation and
member sta access in peer statistics path.
1. Peer creation:
ath10k_peer_create()
=>ath10k_wmi_peer_create()
=>ath10k_wait_for_peer_created()
...
# another kernel path, RX from firmware
ath10k_htt_t2h_msg_handler()
=>ath10k_peer_map_event()
=>wake_up()
# ar->peer_map[id] = peer //add peer to map
#wake up original path from waiting
...
# peer->sta = sta //sta assignment
2. RX path of statistics
ath10k_htt_t2h_msg_handler()
=>ath10k_update_per_peer_tx_stats()
=>ath10k_htt_fetch_peer_stats()
# peer->sta //sta accessing
Any access of peer->sta after peer was added to peer_map but before sta was
assigned could cause a null pointer issue. And because these two steps are
asynchronous, no proper lock can protect them. So both peer and sta need to
be checked before access.

Some hardwares variants (QCA99x0) are limiting msdu deaggregation with
some threshold value(default limit in QCA99x0 is 64 msdus), it was introduced to
avoid excessive MSDU-deaggregation in error cases. When number of sub frames
exceeds the limit, target hardware will send all msdus starting from present
msdu in RAW format as a single msdu packet and it will be indicated with
error status bit "RX_MSDU_END_INFO0_MSDU_LIMIT_ERR" set in rx descriptor.
This msdu frame is a partial raw MSDU and does't have first msdu and ieee80211
header. It caused below warning message.
[ 320.151332] ------------[ cut here ]------------
[ 320.155006] WARNING: CPU: 0 PID: 3 at drivers/net/wireless/ath/ath10k/htt_rx.c:1188
In our issue case, MSDU limit error happened due to FCS error and generated
this warning message.
This fixes the warning by handling the MSDU limit error. If msdu limit error
happens, driver adds first MSDU's ieee80211 header and sets A-MSDU present bit
in QOS header so that upper layer processes this frame if it is valid or drop it
if FCS error set. And removed the warning message, hence partial msdus without
first msdu is expected in msdu limit error cases.

Currently in 10.4 FW, all the received 4addr frames are processed for
source port learning which is enabled by default. This learning can't be
disabled by default in FW since it breaks backward compatibility.
Since ath10k uses mac80211 based 4addr mode, source port learning done in
10.4 FW is redundant and also causes issues when 3addr frames are
transmitted/received for a 4addr station.
One such visible functional impact is when GTK rekey frame from
hostapd based AP to 4addr STA is dropped in AP's 10.4 FW. This is since
GTK rekey EAPOL frame is 3addr frame on AP interface and STA enabled
with 4addr is already allowed for receiving 3addr EAPOL frames.
Source port learning implementation in 10.4 FW drops this 3addr GTK rekey
frame in AP destinated for 4addr STA causing disassociation and
re-association for every GTK rekey session. GTK rekey issue is not seen
when learning is disabled in FW.
To prevent such issues without breaking backward compatibility, FW
advertises new service bit making the source port learning configurable and
this learning is being currently disabled during ath10k vdev creation.

Mesh path metric needs tx rate information from ieee80211_tx_status()
call but in ath10k there is no mechanism to report tx rate information
via ieee80211_tx_status(), the tx rate is only accessible via
sta_statiscs() op.
Per peer tx stats has tx rate info available, Tx rate is available
to ath10k driver after every 4 PPDU sent in the air. For each PPDU,
ath10k driver updates rate informattion to mac80211 using
ieee80211_tx_rate_update().
Per peer txrate information is updated through per peer statistics
and is available for QCA9888/QCA9984/QCA4019/QCA998X only

When processing HTT_T2H_MSG_TYPE_RX_IN_ORD_PADDR_IND, if the length of a msdu
is larger than the tailroom of the rx skb, skb_over_panic issue will happen
when calling skb_put. In monitor mode, amsdu will be handled in this path, and
msdu_len of the first msdu_desc is the length of the entire amsdu, which might
be larger than the maximum length of a skb, in such case, it will hit the issue
upon.
To fix this issue, process msdu list separately for monitor mode.

This issue arise in a race condition between ath10k_sta_state() and
ath10k_htt_fetch_peer_stats(), explained in below scenario
Steps:
1. In ath10k_sta_state(), arsta->tx_stats get deallocated before peer deletion
when the station moves from IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST
state.
2. Meanwhile ath10k receive HTT_T2H_MSG_TYPE_PEER_STATS message.
In ath10k_htt_fetch_peer_stats(), arsta->tx_stats get accessed after
the peer validation check.
Since arsta->tx_stats get freed before the peer deletion [1].
ath10k_htt_fetch_peer_stats() ended up in "use after free" situation.
Fixed this issue by moving the arsta->tx_stats free handling after the
peer deletion. so that ath10k_htt_fetch_peer_stats() will not end up in
"use after free" situation.

Older firmware only supports 16-bit flow handle, because of which the
number of flows that can be offloaded can’t scale beyond a point.
Newer firmware supports 64-bit flow handle enabling the host to scale
upto millions of flows. With the new 64-bit flow handle support, driver
has to query flow stats in a different way compared to the older approach.
This patch adds support for 64-bit flow handle and new way to query

Earlier, some of the firmware commands (ex: CFA_FLOW_*) which are processed
by KONG processor were sent to the CHIMP processor from the host. This
approach was taken as there was no direct message channel to KONG.
CHIMP in turn used to send them to KONG. Newer firmware supports a new
message channel which the host can send messages directly to the KONG
processor.
This patch adds support for required changes needed in the driver
to support direct KONG message channel. This speeds up flow related

transmission from FIFO
The current state of the spi-sh-msiof, in master transfer mode: if t-> bits_per_word <= 8,
if the data length is divisible by 4 ((len & 3) = 0), the length of each word will be 32 bits
In case of data length can not be divisible by 4 ((len & 3) != 0), always set each word to be
8 bits, this will increase the number of times that write to FIFO, increasing the number of
times it should be transmitted. Assume that the number of bytes of data length more than 64 bytes,
each transmission will write 64 times into the TFDR then transmit, a maximum one-time
transmission will transmit 64 bytes if each word is 8 bits long.
Switch to setting if t->bits_per_word <= 8, the word length will be 32 bits although the data

mcp16502_suspend/resume_noirq
mcp16502_suspend/resume_noirq is only used by SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
when CONFIG_PM_SLEEP is defined.
So use #ifdef CONFIG_PM_SLEEP instead CONFIG_SUSPEND guard.

If CONFIG_MLX5_ESWITCH is not defined, test for SR-IOV being disabled,
instead of calling e-switch LAG prereq routine.
Since LAG with SRIOV is allowed only when switchdev mode is on.

In tunnel encap we prepare the encap header for IPv4/6 cases, in two
separate functions. For ETH header generation the code is almost
duplicated.
Move the ETH header generation code from IPv4/6 functions to a helper
function, with no functional change.

Currently we don't support nor fail attempts to offload encap flows routed
to vlan device on the underlay network. We wrongly consider a vlan underlay
device to be on the same e-switch b/c the switchdev ID is retrieved recursively.
Add explicit check for that and fail such attempts.
Also align to a more strict check for the ingress and the underlay devices
to practically be on the same eswitch.

We use the switchdev parent HW id helper to identify if the mirred device
shares the same ASIC/port with the ingress device. This can get us wrong
in the presence of upper devices such as vlan or bridge set over the HW
devices (VF or uplink representors), b/c the switchdev ID is retrieved
recursively.
To fail offload attempts in such cases, we condition the check on the
egress device to have not only the same switchdev ID but also the relevant
mlx5 netdev ops.
