+Subject: [PATCH] wait-online: make manager_link_is_online() return 0 when in
+ unmanaged state
+
+Previously, even if a link is in unmanaged state, the function may
+returns positive value. So, even if all managed links are in the configured
+sate but do not satisfy the online criteria, e.g., IPv4 address state,
+then wait-online finishes with positive value.
+
+This makes the function always return 0 for unmanaged state. So, at
+least one managed link must satisfies the online criteria.
+
+This also adds more comments and debugging logs.
+
+Fixes #22246.
