The dm9000 driver doesn't work in at least one device-tree
configuration, spitting an error message on irq resource :
[ 1.062495] dm9000 8000000.ethernet: insufficient resources
[ 1.068439] dm9000 8000000.ethernet: not found (-2).
[ 1.073451] dm9000: probe of 8000000.ethernet failed with error -2
The reason behind is that the interrupt might be provided by a gpio
controller, not probed when dm9000 is probed, and needing the probe
deferral mechanism to apply.
Currently, the interrupt is directly taken from resources. This patch
changes this to use the more generic platform_get_irq(), which handles
the deferral.
Moreover, since commit Fixes: 7085a7401ba5 ("drivers: platform: parse
IRQ flags from resources"), the interrupt trigger flags are honored in
platform_get_irq(), so remove the needless code in dm9000.

This change makes it so that if UDP CSUM is not specified we will default
to enabling it. The main motivation behind this is the fact that with the
use of outer checksum we can greatly improve the performance for VXLAN

SW data field in descriptor can be used by software to hold private
data for the driver. As there are 4 words available for this purpose,
use separate macros to place it or retrieve the same to/from
descriptors. Also do type cast of data types accordingly.

Rename the pad to sw_data as per description of this field in the hardware
spec(refer sprugr9 from www.ti.com). Latest version of the document is
at http://www.ti.com/lit/ug/sprugr9h/sprugr9h.pdf and section 3.1
Host Packet Descriptor describes this field.
Define and use a constant for the size of sw_data field similar to
other fields in the struct for desc and document the sw_data field
in the header. As the sw_data is not touched by hw, it's type can be
changed to u32.
Rename the helpers to match with the updated dma desc field sw_data.

The commit 899077791403 ("netcp: try to reduce type confusion in
descriptors") introduces a regression in Kernel 4.5-rc1 and it breaks
get/set_pad_info() functionality.
The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to
store DMA/MEM buffer pointer and buffer size respectively. And in both
cases for Keystone 2 the pointer type size is 32 bit regardless of
LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally
is not expected to be defined.
Unfortunately, above commit changed buffer's pointers save/restore
code (get/set_pad_info()) and added intermediate conversation to u64
which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver
crash in RX/TX path due to "Unable to handle kernel NULL pointer"
exception. This issue was reported and discussed in [1].
Hence, fix it by partially reverting above commit and restoring
get/set_pad_info() functionality as it was before.

This patch fixes the problem that more CAN messages could be sent to the
interface as could be send on the CAN bus. This was more likely for slow baud
rates. The sleeping _start_xmit was woken up in the _write_bulk_callback. Under
heavy TX load this produced another bulk transfer without checking the
free_slots variable and hence caused the overflow in the interface.

Technologic Systems provides an IP compatible with the SJA1000,
instantiated in an FPGA. Because of some bus widths issue, access to
registers is made through a "window" that works like this:
base + 0x0: address to read/write
base + 0x2: 8-bit register value

The PHY link state is not chaged in GENETv2 caused by the previous
commit 49f7a471e4d1 ("net: bcmgenet: Properly configure PHY to ignore
interrupt") was set to PHY_IGNORE_INTERRUPT in bcmgenet_mii_probe().
The internal PHY should use phy_mac_interrupt() when not in use
PHY_POLL. The statement for phy_mac_interrupt() has two conditions. The
first condition to check GENET_HAS_MDIO_INTR is not related PHY link
state, so this patch removes it.

For i40e driver, each vector has its own ITR register. However, there
are no concept of queue-specific settings in the driver proper. Only
global variable is used to store ITR values. That will cause problems
especially when resetting the vector. The specific ITR values could be
lost.
This patch move rx_itr_setting and tx_itr_setting to i40e_ring to store
specific ITR register for each queue.
i40e_get_coalesce and i40e_set_coalesce are also modified accordingly to
support queue-specific settings. To make it compatible with old ethtool,
if user doesn't specify the queue number, i40e_get_coalesce will return
queue 0's value. While i40e_set_coalesce will apply value to all queues.

Thermal hook gpio_fan_get_cur_state is only interested in knowing
the current speed index that was setup in the system, this is
already available as part of fan_data->speed_index which is always
set by set_fan_speed. Using get_fan_speed_index is useful when we
have no idea about the fan speed configuration (for example during
fan_ctrl_init).
When thermal framework invokes
gpio_fan_get_cur_state=>get_fan_speed_index via gpio_fan_get_cur_state
especially in a polled configuration for thermal governor, we
basically hog the i2c interface to the extent that other functions
fail to get any traffic out :(.
Instead, just provide the last state set in the driver - since the gpio
fan driver is responsible for the fan state immaterial of override, the
fan_data->speed_index should accurately reflect the state.

The purpose of gigaset_device_release() is to kfree() the struct
ser_cardstate that contains our struct device. This is done via a bit of
a detour. First we make our struct device's driver_data point to the
container of our struct ser_cardstate (which is a struct cardstate). In
gigaset_device_release() we then retrieve that driver_data again. And
after that we finally kfree() the struct ser_cardstate that was saved in
the struct cardstate.
All of this can be achieved much easier by using container_of() to get
from our struct device to its container, struct ser_cardstate. Do so.
Note that at the time the detour was implemented commit b8b2c7d845d5
("base/platform: assert that dev_pm_domain callbacks are called
unconditionally") had just entered the tree. That commit disconnected
our platform_device and our platform_driver. These were reconnected
again in v4.5-rc2 through commit 25cad69f21f5 ("base/platform: Fix
platform drivers with no probe callback"). And one of the consequences
of that fix was that it broke the detour via driver_data. That's because
it made __device_release_driver() stop being a NOP for our struct device
and actually do stuff again. One of the things it now does, is setting
our driver_data to NULL. That, in turn, makes it impossible for
gigaset_device_release() to get to our struct cardstate. Which has the
net effect of leaking a struct ser_cardstate at every call of this
driver's tty close() operation. So using container_of() has the
additional benefit of actually working.

- Hide unused functions in the Nomadik driver.
- Fix up direction control in the Mediatek driver.

If we reset a VF, its VSI goes away, and it gets a new one. So don't
hang on to the now-stale local VSI pointer. It just leads to suffering
and kernel panics.

We need to suspend scheduling or any pending service task during driver
unload process, so that new task will not be scheduled. This patch sets
the suspend flag bit during reload which avoids service task execution.

Use the new AdminQ functions for safely accessing the Rx control
registers that may be affected by heavy small packet traffic.
We can't use AdminQ calls in i40e_clear_hw() because the HW is being
initialized and the AdminQ is not alive. We recently added an AQ
related replacement for reading PFLAN_QALLOC, and this patch puts
back the original register read.

Add the new opcodes and struct used for asking the firmware to update Rx
control registers that need extra care when being accessed while under
heavy traffic - e.g. sustained 64byte packets at line rate on all ports.
The firmware will take extra steps to be sure the register accesses
are successful.
The registers involved are:
PFQF_CTL_0
PFQF_HENA
PFQF_FDALLOC
PFQF_HREGION
PFLAN_QALLOC
VPQF_CTL
VFQF_HENA
VFQF_HREGION
VSIQF_CTL
VSILAN_QBASE
VSILAN_QTABLE
VSIQF_TCREGION
PFQF_HKEY
VFQF_HKEY
PRTQF_CTL_0
GLFCOE_RCTL
GLFCOE_RSOF
GLQF_CTL
GLQF_SWAP
GLQF_HASH_MSK
GLQF_HASH_INSET
GLQF_HSYM
GLQF_FC_MSK
GLQF_FC_INSET
GLQF_FD_MSK
PRTQF_FD_INSET
PRTQF_FD_FLXINSET
PRTQF_FD_MSK

Return from i40e_vsi_reinit_setup() if vsi param is NULL.
This makes this code consistent with all the other code that
checks for NULL before using one of the VSI pointers accessed
with an indexed variable. (Indexed VSI pointers are
intentionally set to NULL in i40e_vsi_clear() and
i40e_remove().

This fixes an issue where a previously removed message
has returned. Changing the message type to dev_dbg
leaves the info, if desired, but takes it out of normal
everyday usage. Also changed call to only provide port
data when its valid and not when its not (delete case).

Just like Tx queues don't wait for Rx queues to be disabled before
DCB has been reconfigured.
Check the queues are disabled only after the DCB configuration has
been applied to the VSI(s) managed by the PF driver.
In case of any timeout issue a PF reset to recover.

When linking with particular PHY types (ex: copper PHY), the amount of
time it takes for the GLGEN_RSTAT_DEVSTATE to be set increases greatly,
which can lead to a timeout and failure to load the driver.

This patch fixes a problem where the ethtool identify adapter
functionality did not work for some copper PHY's. Without this
patch, the blink led functionality fails on some parts. This
patch adds PHY write code to blink led's on parts where this
functionality is contained in the PHY rather than the MAC.
