Ben Hutchings 71839f7d16 sfc: Distinguish critical and non-critical over-temperature conditions
Set both the 'maximum' and critical temperature limits for LM87
hardware monitors on Falcon boards.  Do not shut down a port until the
critical temperature is reached, but warn as soon as the 'maximum'
temperature is reached.

Ben Hutchings f18ca36461 sfc: Reduce log level for MCDI error response in efx_mcdi_rpc()
Some errors are expected, e.g. when sending new commands to an MC
running old firmware.  Only the caller of efx_mcdi_rpc() can decide
what is a real error.  Therefore log the error responses with
netif_dbg().

Vlad Lungu f8e9616108 stmmac: priv->lock can be used uninitialized
To reproduce: if connman (http://connman.net/) is started,
inserting the stmmac module triggers a "BUG: spinlock bad magic on CPU#0".

Registering the device in stmmac_probe() sends a notification to connman
which brings the interface up before the lock is initialized.

Felix Fietkau e702ba18f2 ath9k_hw: fix endian issues with CTLs on AR9003
Parsing data using bitfields is messy, because it makes endian handling
much harder. AR9002 and earlier got it right, AR9003 got it wrong.
This might lead to either using too high or too low tx power values,
depending on frequency and eeprom settings.
Fix it by getting rid of the CTL related bitfields entirely and use
masks instead.

Dmitry Kravkov 0793f83f0e bnx2x: Add Nic partitioning mode (57712 devices)
NIC partitioning is another flavor of multi function - having few
PCI functions share the same physical port. Unlike the currently
supported mode of multi-function which depends on the switch
configuration and uses outer-VLAN, the NPAR mode is switch independent
and uses the MAC addresses to distribute incoming packets to the different
functions. This patch adds the specific HW setting of the NPAR mode
and some distinctions between switch dependent (SD) and
switch independent (SI) multi-function (MF) modes where the configuration
is not the same.

Hauke Mehrtens 6c08af0302 b44: fix workarround for wap54g10
The code for the b44_wap54g10_workaround was never included, because
the config option was wrong. The nvram_get function was never in
mainline kernel, only in external OpenWrt patches.

The code should be compiled in when CONFIG_BCM47XX is selected and not
when CONFIG_SSB_DRIVER_MIPS is selected, because nvram_getenv is only
available on bcm47xx platforms and now in the mainline kernel code.
Using an include is better than a second function declaration, to fix
this when the function signature changes.

 modes indicates there is a bit on bank 2 related to turbo operation
 (it's set on turbo modes). This bit is present on all radios except
 RF5413 that seems to have a completely different bank 2. Also
 since 2317 has the same rf-registers locations with 2425 and
 since the bit exists on 2317 I assume it also exists on 2425/2417).

Nick Kossifidis 8aec7af99b ath5k: Support synth-only channel change for AR2413/AR5413
* Add synth-only channel change for AR2413/5413. When we call
 ath5k_reset with a channel ath5k_hw_reset will first try to
 set channel on PHY while PHY is running instead of doing a normal
 full reset. To do this phy_init has to change to implement this
 functionality.

 * Clean up change_channel flag, what it really did was skip PCU
 registers when setting initvals. This is done because on reset
 PCU registers are not affected (except the registers we set
 in pcu init and -due to hw problems- TSF). Use a new skip_pcu
 flag that's not misleading instead. In the future we might use
 that to also skip PCU reset and save us the TSF etc problems
 (needs testing because standard practice is to reset everything).

 * Use fast channel change only when setting channel, and set skip_pcu
 to false only on init. When we reset the card due to DMA or PHY
 problems skip pcu but never do a fast channel change.

This feature is to mitigate the problem of certain 3
stream chips that exceed the PCIe power requirements.An EEPROM flag
controls which chips have APM enabled which is basically read from
miscellaneous configuration element of the EEPROM header.

This workaround will reduce power consumption by using 2 Tx chains for
Single and Double stream rates (5 GHz only).All self generated frames
(regardless of rate) are sent on 2 chains when this feature is
enabled(Chip Limitation).

Yang Li d830418e40 ucc_geth: fix ucc halt problem in half duplex mode
In commit 58933c64(ucc_geth: Fix the wrong the Rx/Tx FIFO size),
the UCC_GETH_UTFTT_INIT is set to 512 based on the recommendation
of the QE Reference Manual.  But that will sometimes cause tx halt
while working in half duplex mode.

According to errata draft QE_GENERAL-A003(High Tx Virtual FIFO
threshold size can cause UCC to halt), setting UTFTT less than
[(UTFS x (M - 8)/M) - 128] will prevent this from happening
(M is the minimum buffer size).

The patch changes UTFTT back to 256.

Jonas Bonn 8dac428ae9 ethoc: rework mdio read/write
MDIO read and write were checking whether a timeout had expired to determine
whether to recheck the result of the MDIO operation.  Under heavy CPU usage,
however, it was possible for the timeout to expire before the routine got
around to be able to check a second time even, thus erroneousy returning an
-EBUSY.

This patch changes the the MDIO IO routines to try up to five times to complete
the operation before giving up, thus lessening the dependency on CPU load.

This resolves a problem whereby a ping flood would keep the CPU so busy that
the above problem would manifest itself; the MDIO command to check link status
would fail and the interface would erroneously be shut down.
