Kevin Darbyshire-Bryant 3413e97dbb ath10k: suppress 'failed to process fft' warning messages
When using DFS channels on Ath10k, kernel log has repeated warning message
'failed to process fft: -22' typically under medium/heavy traffic.

This patch switches the warnings to driver debug (WMI events) mode only
thus reducing log file noise.

DFS and spectral scan share underlying HW mechanisms and enabling one
(DFS) enables the other (spectral scan) as far as event reporting from
firmware to driver is concerned. Spectral scan events take no part in
processing of DFS radar pulses which are delivered as distinct events,
so the fft (spectral event) warning is harmless and DFS interference
detection/protection still occurs.

Symptoms seen & fix tested in both debug & non-debug modes on TP-Link
Archer C7 v2 platform.

Raja Mani 1d0088f8c1 ath10k: extend struct htt_mgmt_tx_dec for qca99x0
HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
rate mgmt frame has to go out in the air. It's an optional parameter,
setting this field to zero will force firmware to choose auto rate
and send the frame out.

Those 4 byte info is missed out in the current code and 10.4 firmware
ended up reading some junk in those 4 byte and sometime malfunctioning.

Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
will not process those four byte. So, adding 4 byte at the end of
struct htt_mgmt_tx_desc will not create any impact on other chipset.

Peter Oh 1f5dbfbb64 ath10k: add support for qca99x0 Rx descriptors
QCA99X0 chip has an extra 4 bytes in rx_msdu_start,
20 bytes in rx_msdu_end and 20 bytes in rx_ppdu_end structure
which are used in htt_rx_desc and HTT Rx ring offset setup.
This is necessary for correct Rx for QCA99X0 or Rx descriptors

desc base addr + msdu id, so that hardware can retrieve

Vasanthakumar Thiagarajan acd195800f ath10k: delay device access after cold reset
It is observed that during cold reset pcie access right
after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
Data Bus Error and system hard lockup. The reason
for bus error is that pcie needs some time to get
back to stable state for any transaction during cold reset. Add
delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
to fix this issue. This patch is tested on QCA988X. This is
also tested on QCA99X0 which is WIP.

Zefir Kurtisi 8fc2b61a36 ath9k: DFS - add pulse chirp detection for FCC
FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.

A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range

The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done

only after the cmd completes while the MCCQ is locked).

The existing code takes the updated MTU value only from the host side.
But vSwitch extensions, such as Open vSwitch, require the flexibility
to change the MTU to different values from within a guest during the
lifecycle of a vNIC, when the encapsulation protocol is changed. The
patch supports this kind of MTU changes.

Eric Dumazet 9e29e21a9b ifb: add multiqueue operation
Add multiqueue capabilities to ifb netdevice.

This removes last bottleneck for ingress when mq qdisc can be used
to shard load from multiple RX queues on physical device.

Tested:

# netem based setup, installed at receiver side
ETH=eth0
IFB=ifb10
EST="est 1sec 4sec" # Optional rate estimator
RTT_HALF=2ms
#REORDER=20us
#LOSS="loss 1"
TXQ=8

ip link add ifb10 numtxqueues $TXQ type ifb
ip link set dev $IFB up

tc qdisc add dev $ETH ingress 2>/dev/null

tc filter add dev $ETH parent ffff: \
   protocol ip u32 match u32 0 0 flowid 1:1 \
	action mirred egress redirect dev $IFB

tc qdisc del dev $IFB root 2>/dev/null

tc qdisc add dev $IFB root handle 1: mq
for i in `seq 1 $TXQ`
do
 slot=$( printf %x $(( i )) )
 tc qd add dev $IFB parent 1:$slot $EST netem \
	limit 100000 delay $RTT_HALF $REORDER $LOSS
done

Hariprasad Shenai fda8b18c51 cxgb4: Fix incorrect sequence numbers shown in devlog
Part of commit 49aa284fe64c4c1 ("cxgb4: Add support for devlog")
change introduced a real bug where the Device Log Sequence Numbers are
no longer being converted from firmware Big-Endian to local CPU-Endian
format.

This patch moves all of the translation into the devlog_show() routine.
The only endianness code now in devlog_open() is the small loop to find the
earliest (lowest Sequence Number) Device Log entry in the circular buffer.
