During the transition of privilege levels while performing syscalls,
the ARM documentation recommends flushing the pipeline to avoid
pre-fetched instructions from being executed with the previous
privilege level.
The manual says:
4.16 CONTROL register
(...) after programming the CONTROL register, an ISB instruction
should be used.
(...) This is not implemented in the Cortex M0 processor.

Min RAM requirement for tests/net/utils was 16K,
hence run on nucleo_l073rz.
Though, build size is a little more than 20K which
overflows board RAM.
Increase min RAM requirement for this test to 24K

The test "net/utils" fails to build on nucleo_f103rb
due to "region `SRAM' overflowed by 8 bytes.

Moreover, according to issue #6858, we will only configure
board valuable HW and connectors on board level and the
user should enable what is needed on application level.

If we have multiple network interfaces and we want to send
a IPv4 network packet to certain destination, then this new
helper can be used to figure out what network interface to use.
Note that this commit only adds support to select the correct network
interface according to destination IPv4 address. This does not enable
any automatic routing to happen.

boards/x86/arduino_101/arduino_101_defconfig currently enables
CONFIG_UART_QMSI_0_HW_FC (HW flow control on UART 0), but doesn't enable
CONFIG_UART_QMSI_0 (the UART itself), which is a direct dependency.
This means CONFIG_UART_QMSI_0_HW_FC remains disabled despite the request
to enable it, and kconfig.py prints a warning.
Enable CONFIG_UART_QMSI_0 in the arduino_101_defconfig.

If a large size is requested, the expression `size += sizeof(...)`
might overflow, leading to a small block being requested and returned
by k_malloc().

The simple function that helps to integrate nrfx IRQ handlers with
the IRQ_CONNECT macro can be used in shims for various nrfx drivers,
not only the SPI one.
Similarly, the macro for getting the IRQ number from the peripheral
base address needs to be widely available. It should be even moved
to <nrfx_common.h> in some next nrfx update.

Exposing connect, disconnect and scan for now.
In case the iface is an instance of a WiFi offload device, the way it
manages scanning, connecting and disconnecting will be specific to that
device (not the mgmt interface obviously). In such case the device will
have to export relevantly a dedicated bunch of function to serve the
mgmt interface in a generic way.
