Add this new command for 82599 and x540 devices only. Support for other
devices will be added later.
82599 and x540 VFs and PF share the same RSS redirection table (RETA).
Therefore we just return it for all VFs.
For 82599 and x540 RETA table is an array of 32 registers (128 bytes) and
the maximum number of registers that may be delivered in a single VF-PF
channel command is 15. On the other hand VFs of these devices can be
configured to have up to 4 RSS queues. Therefore we will "compress" the
RETA by transferring only 2 bits per entry and thereby it will take only 8
registers (DWORDS) to transfer the whole VF RETA.
Thus this patch does the following:
- Adds a new API version (to specify a new commands set).
- Adds the IXGBE_VF_GET_RETA command to the VF-PF commands set.

This patch is a preparation for enablement of ethtool RSS indirection
table and hash key querying. We don't want to read registers every time
the RSS info is queried. Therefore we will store its current content in the
arrays in the adapter struct and will read it from there (instead of from
registers) when requested.
Will change the code that writes the indirection table and hash key into
the HW registers to take its content from these arrays. This will also
simplify the indirection table updating ethtool callback implementation
in the future.

HID Sensor Spec defines two usage ids for custom sensors
HID_USAGE_SENSOR_TYPE_OTHER_CUSTOM (0x09, 0xE1)
HID_USAGE_SENSOR_TYPE_OTHER_GENERIC(0x09, 0xE2)
In addition the standard also defines usage ids for custom fields.
The purpose of these sensors is to extend the functionality or provide a way to
obfuscate the data being communicated by a sensor. Without knowing the mapping
between the data and its encapsulated form, it is difficult for an driver to
determine what data is being communicated by the sensor. This allows some
differentiating use cases, where vendor can provide applications. Since these
can't be represented by standard sensor interfaces like IIO, we present these
as fields with
- type (input/output)
- units
- min/max
- get/set value
In addition an dev interface to transfer report events. Details about this
interface is described in /Documentation/hid/hid-sensor.txt. Manufacturers
should not use these ids for any standard sensors, otherwise the the
product/vendor id can be added to black list.

This fixes a oops due to a double list add when adding a reject PDU for
iscsit_allocate_iovecs allocation failures. The cmd has already been
added to the conn_cmd_list in iscsit_setup_scsi_cmd, so this has us call
iscsit_reject_cmd.
Note that for ERL0 the reject PDU is not actually sent, so this patch
is not completely tested. Just verified we do not oops. The problem is the
add reject functions return -1 which is returned all the way up to
iscsi_target_rx_thread which for ERL0 will drop the connection.

In cases of short transfer times the CPU is spending lots of time
in the interrupt handler and scheduler to reschedule the worker thread.
Measurements show that we have times where it takes 29.32us to between
the last clock change and the time that the worker-thread is running again
returning from wait_for_completion_timeout().
During this time the interrupt-handler is running calling complete()
and then also the scheduler is rescheduling the worker thread.
This time can vary depending on how much of the code is still in
CPU-caches, when there is a burst of spi transfers the subsequent delays
are in the order of 25us, so the value of 30us seems reasonable.
With polling the whole transfer of 4 bytes at 10MHz finishes after 6.16us
(CS down to up) with the real transfer (clock running) taking 3.56us.
So the efficiency has much improved and is also freeing CPU cycles,
reducing interrupts and context switches.
Because of the above 30us seems to be a reasonable limit for polling.

Transforms the bcm-2835 native SPI-chip select to their gpio-cs equivalent.
This allows for some support of some optimizations that are not
possible due to HW-gliches on the CS line - especially filling
the FIFO before enabling SPI interrupts (by writing to CS register)
while the transfer is already in progress (See commit: e3a2be3030)
This patch also works arround some issues in bcm2835-pinctrl which does not
set the value when setting the GPIO as output - it just sets up output and
(typically) leaves the GPIO as low. When a fix for this is merged then this
gpio_set_value can get removed from bcm2835_spi_setup.
