Enable native posix ethernet driver. Note, this driver is run inside

a process in your host system.

|

If set, the native_posix ethernet driver will set up the network
|
|
interface, requiring ``zephyr.exe`` to be run with root privileges
|
|
(needed to create and configure the TAP device).
|
|
If not set (the default and recommended way), the network interface
|
|
must be set up manually using ``net-setup.sh`` (from the net-tools
|
|
project repo). The ``zephyr.exe`` program can then be run as a
|
|
non-root user.

|
|
This option sets the name of the script that is run when the host TAP
|
|
network interface is created. The script should setup IP addresses
|
|
etc. for the host TAP network interface.
|
|
The default script accepts following options:
|
|
-i|--interface <network interface name>, default is zeth
|
|
-f|--file <config file name>, default is net_setup_host.conf
|
|
If needed, you can add these options to this script name option.
|
|
Note that the driver will add -i option with the value of
|
|
CONFIG_ETH_NATIVE_POSIX_DRV_NAME option to the end of the options
|
|
list when calling the host setup script.

help
|

This option sets the name of the script that is run when the host TAP
|
|
network interface is created and setup script has been run.
|
|
The startup script could launch e.g., wireshark to capture
|
|
the network traffic for the freshly started network interface.
|
|
Note that the network interface name CONFIG_ETH_NATIVE_POSIX_DRV_NAME
|
|
is appended at the end of this startup script name.
|
|
Example script for starting wireshark is provided in
|
|
${ZEPHYR_BASE}/samples/net/eth_native_posix/net_start_wireshark.sh
|
|
file.

By default the startup script is run as a root user. Set here the
|
|
username to run the script if running it as a root user is not
|
|
desired. Note that this setting is only for startup script and not
|
|
for the setup script. The setup script needs to be run always as
|
|
a root user.

six hex 8-bit chars separated by colons (e.g.:
