Subject: [PATCH] network: fix carrier detection
|
|
|
|
rename iface_has_link() to iface_has_carrier() to clarify usage
|
|
|
|
Only assign static "wildcard interface" settings, if the interface has a
|
|
carrier.
|
|
|
|
If the interface name was specified with a name, do not do carrier
|
|
checking for static configurations.
