The key-mgmt property of NMSettingWirelessSecurity is slightly confusing
when you know there's also a wpa_supplicant configuration option called
"key_mgmt". Our property is not the same as that supplicant option even
though they do have things in common. NMs key-mgmt is not exactly meant
to configure which AKM suites you want to use, but rather which method
of wifi security is being used (so "wpa2+wpa3 personal", "wpa3 personal
only" or "wpa3 enterprise only").
Try to make this a bit clearer in the documentation of the property by
rewriting it and listing those security methods.
This patch is introducing the wired setting accept-all-mac-addresses
property. The value corresponds to the kernel flag IFF_PROMISC.
When accept-all-mac-address is enabled, the interface will accept all
the packets without checking the destination mac address.
