I haven't been following NM development lately. Just wondering: is
there an option to explicitly select IPV4LL for configuring an IP
address, instead of relying on dhcp-with-ipv4ll-fallback? This could
be very useful for speeding up configuration in networks where most
likely no dhcp is around, such as wlan ad-hoc, bluetooth pan, ethernet
cross cable, usb-to-usb, ... Those ad-hoc networks are usually created
_ad hoc_ i.e. temporarily, and thus configuration should be quick. So
it'd be best if nm wouldn't do dhcp in these situations to avoid the
long timeout. i.e. what I am thinking is: besides "dhcp" and "static"
configuration for network interfaces, allow a special "zeroconf"
configuration option. For the aforementioned ad-hoc network types
default to "zeroconf", for the others to "dhcp" -- and then, allow
people to switch to the other mode if they are so crazy to have a wlan
ad-hoc network with dhcp, or a wlan infrastracture network without.
