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. |
|
|
|
(cherry picked from commit df95b1003c8e7564da73de92403013763eb028fe) |
