+
+- `device` (String) Name of the interface device.
+
+### Read-Only
+
+- `capabilities` (Set of String) List of capabilities the interface supports.
+- `flags` (Set of String) List of flags configured on the interface (equiv. to flags=xxxx in output of ifconfig).
+- `groups` (Set of String) List of groups the interface is a member of.
