When changing the device from or to promisc mode this only affects the
device after the device is bought up the next time. For bridging it is
needed to change the device to promisc mode while it is up, which is
possible with this patch.

Setting up IPv6 addresses on configurations with many macvlans
is not really working, as many multicast messages are dropped.
Add a multicast filter to macvlan to reduce the amount of cloned
skbs and overhead.

Some modes don't require any special carrier handling so
in these cases, the kernel can control the carrier as for
any other interface. However, some other modes, e.g. lacp,
requires more than just that, so userspace needs to control
the carrier itself.
The daemon today is ready to control it, but the kernel
still can change it based on events.
This fix so that either kernel or userspace is controlling
the carrier.

All in-kernel users of class_find_device() don't really need mutable
data for match callback.
In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c)
this patch changes match callbacks to use const search data.
The const is propagated to rtc_class_open() and power_supply_get_by_name()
parameters.
Note that there's a dev reference leak in suspend_test.c that's not

For PMBus chips, modifying one limit register may affect other limits.
Since limits are all cached in the PMBus core driver, related changes

Some PMBus chips support monitoring an additional non-standard voltage. While
this voltage can in many cases be supported by simulating an additional sensor
page, this does not work in all cases. Specifically, it is problematic if the
data format is linear and the voltage is reported in LINEAR11 format. Since
output voltages use LINEAR16, and the exponent for LINEAR16 data is chip-wide
and fixed, this can result in overflows.
To solve this problem, add support for an additional virtual input voltage,
call it 'vmon', and treat this voltage as input voltage (which, when the chip
supports linear data format, uses LINEAR11).

So far, attribute memory was allocated by pre-calculating the maximum possible
amount of attributes. Not only does this waste memory, it is also risky because
the calculation might be wrong. It also requires a lot of defines to specify
the maximum number of attributes per class.
Allocate attribute memory using krealloc() instead. That means we have to use
kfree(), since devm_krealloc() does not exist, but that is still less costly
and less risky than trying to predict the number of attributes at the beginning.

Boolean handling depends on storing the sensor data index in sensor_device_attr
as part of the index variable. This limits the number of sensor attributes to
256, and means the sensor sequence number actually has to be maintained to be
able to access sensor data from boolean functions.
Rework the code to store sensor pointers in the pmbus_boolean data structure
directly. With this approach, the number of supportable sensors is now
unlimited.

Without this patch, the SHT15 driver may fail silently with a
non-bidirectional data line and/or an input-only clock line.
This patch checks the return value of gpio_direction_* function calls
and returns the error code (if any) to the caller. If an error occurs in
the read work function (work_funct_t), we wake the queue up directly
without updating the data->state flag, to notice the waiter of the I/O
error.
The patch also makes minor cleanups: s/error_ret/unlock for some labels
and uses devm_gpio_request_one() for the clock line.
