Currently "src/" mostly contains the source code of the daemon. I say mostly, because that is not true, there are also the device, settings, wwan, ppp plugins, the initrd generator, the pppd and dhcp helper, and probably more. Also we have source code under libnm-core/, libnm/, clients/, and shared/ directories. That is all confusing. We should have one "src" directory, that contains subdirectories. Those subdirectories should contain individual parts (libraries or applications), that possibly have dependencies on other subdirectories. There should be a flat hierarchy of directories under src/, which contains individual modules. As the name "src/" is already taken, that prevents any sensible restructuring of the code. As a first step, move "src/" to "src/core/". This gives space to reorganize the code better by moving individual components into "src/". For inspiration, look at systemd's "src/" directory. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/743

/* By default, NML3IPv4LL is disabled. You also need to register (enable) it.
|
|
* The intent of this API is that multiple users can enable/register their own
|
|
* settings, and NML3IPv4LL will mediate the different requests.
|
|
*
|
|
* Also, by setting timeout_msec to zero, NML3IPv4LL is disabled again (zero
|
|
* wins over all timeouts). This is useful if you do DHCP and IPv4LL on the
|
|
* same interface. You possibly want to disable IPv4LL if you have a valid
|
|
* DHCP lease. By registering a timeout_msec to zero, you can disable IPv4LL.
|
|
*
|
|
* Also, a registration keeps the NML3IPv4LL instance alive (it also takes
|
|
* a reference). */
