ae469b68a5 cxgb4: Fix to dump devlog, even if FW is crashed
Add new Common Code routines to retrieve Firmware Device Log
parameters from PCIE_FW_PF[7]. The firmware initializes its Device Log very
early on and stores the parameters for its location/size in that register.
Using the parameters from the register allows us to access the Firmware
Device Log even when the firmware crashes very early on or we're not
attached to the firmware

ba8c3d6f16 mac80211: add an intermediate software queue implementation
This allows drivers to request per-vif and per-sta-tid queues from which
they can pull frames. This makes it easier to keep the hardware queues
short, and to improve fairness between clients and vifs.

The task of scheduling packet transmission is left up to the driver -
queueing is controlled by mac80211. Drivers can only dequeue packets by
calling ieee80211_tx_dequeue. This makes it possible to add active queue
management later without changing drivers using this code.

This can also be used as a starting point to implement A-MSDU
aggregation in a way that does not add artificially induced latency.

5f919abc76 mac80211: add standard deviation to Minstrel stats
This patch adds the statistical descriptor "standard deviation"
to better describe the current properties of Minstrel and
Minstrel-HTs success probability distribution. The standard
deviation (SD) is calculated as exponential weighted moving
standard deviation (EWMSD) and its current value is added as
new column in all rc_stats (in debugfs).

8d88c6ebb3 net: bcmgenet: enable MoCA link state change detection
Currently, MoCA fixed PHYs are always in link-up state, regardless of
whether the link is actually up or not.

Add code to properly detect MoCA link state changes and to reflect the
new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of
detecting MoCA link state changes.

The code works as follows:
1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP
   or UMAC_IRQ_LINK_DOWN interrupt.
2. Link up/down interrupt is processed in bcmgenet_irq_task(), which
   calls phy_mac_interrupt().
3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks
   the PHY state machine.
4. PHY state machine proceeds to read the fixed PHY link status
   register.
5. When the fixed PHY link status register is being read, the new
   function bcmgenet_fixed_phy_link_update() gets called. It copies
   the fixed PHY phydev->link value to the fixed PHY status->link.
6. PHY state machine receives the new link state of the fixed PHY.
7. MoCA fixed PHY link state now correctly reflects the real MoCA
   hardware link state.

039a0051ec ath10k: allocate fw resources for iface combinations
The number of 3 vdevs wasn't enough to handle the
worst case for interface combinations in practice.

wpa_supplicant may need up to 4 vifs to have 2
vifs actually connected, i.e. p2pdev + client + 2x
p2p (either p2p client or p2p go).

This fixes worst case warning:

  Free vdev map is empty, no more interfaces allowed.

This keeps the ability to associate 32 stations in
AP mode at the cost of not being able to guarantee
that under all circumstances, i.e. some
combinations may consume additional fw peer
entries for internal purposes leaving less
resource for stations in AP mode.

c94aa7ef46 ath10k: fix survey reporting
Number of channels is stored in a separate macro
in a header file and channel list is constructed
independently. The macro is used to define survey
array.

This fixes a recent regression introduced after
adding support for 144 channel. The regression
would lead to a warning and incomplete survey data
on channel 165:

  chan info: invalid frequency 5825 (idx 38 out of bounds)

Also make sure to enforce the sizes and avoid this
kind of problem in the future.

to fit this model.

Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Moreover use devm_gpiod_get_optional instead of ignoring all errors
returned by devm_gpiod_get and simplify accordingly.

The result is more strict error handling which is good.

da254fbc63 bnx2x: Fix kdump when iommu=on
When IOMM-vtd is active, once main kernel crashes unfinished DMAE transactions
will be blocked, putting the HW in an error state which will cause further
transactions to timeout.

Current employed logic uses wrong macros, causing the first function to be the
only function that cleanups that error state during its probe/load.

This patch allows all the functions to successfully re-load in kdump kernel.

3d6b72534a bnx2x: Fix kdump on 4-port device
When running in a kdump kernel, it's very likely that due to sync. loss with
management firmware the first PCI function to probe and reach the previous
unload flow would decide it can reset the chip and continue onward. While doing
so, it will only close its own Rx port.

On a 4-port device where 2nd port on engine is a 1g-port, the 2nd port would
allow ingress traffic after the chip is reset [assuming it was active on the
first kernel]. This would later cause a HW attention.

This changes driver flow to close both ports' 1g capabilities during the
previous driver unload flow prior to the chip reset.
