+ *
+
+Usage of the library functions:
+
+ The main datastructure for a switch is the struct switch_device
+ To get started, you first need to use switch_connect() to probe
+ for switches and allocate an instance of this struct.
+
+ There are two possible usage modes:
+ dev = switch_connect("eth0");
+ - this call will look for a switch registered for the linux device
+ "eth0" and only allocate a switch_device for this particular switch.
+
+ dev = switch_connect(NULL)
+ - this will return one switch_device struct for each available
+ switch. The switch_device structs are chained with by ->next pointer
+
+ Then to query a switch for all available attributes, use:
+ swlib_scan(dev);
+
+ All allocated datastructures for the switch_device struct can be freed with
+ swlib_free(dev);
+ or
+ swlib_free_all(dev);
+
+ The latter traverses a whole chain of switch_device structs and frees them all
+
+ Switch attributes (struct switch_attr) are divided into three groups:
+ dev->ops:
+ - global settings
+ dev->port_ops:
+ - per-port settings
+ dev->vlan_ops:
+ - per-vlan settings
+
+ switch_lookup_attr() is a small helper function to locate attributes
+ by name.
+
+ switch_set_attr() and switch_get_attr() can alter or request the values
+ of attributes.
+
+Usage of the switch_attr struct:
+
+ ->atype: attribute group, one of:
+ - SWLIB_ATTR_GROUP_GLOBAL
+ - SWLIB_ATTR_GROUP_VLAN
+ - SWLIB_ATTR_GROUP_PORT
+
+ ->id: identifier for the attribute
+
+ ->type: data type, one of:
+ - SWITCH_TYPE_INT
+ - SWITCH_TYPE_STRING
+ - SWITCH_TYPE_PORT
+
+ ->name: short name of the attribute
+ ->description: longer description
+ ->next: pointer to the next attribute of the current group
+
+
+Usage of the switch_val struct:
+
+ When setting attributes, following members of the struct switch_val need
+ to be set up:
+
+ ->len (for attr->type == SWITCH_TYPE_PORT)
+ ->port_vlan:
+ - port number (for attr->atype == SWLIB_ATTR_GROUP_PORT), or:
+ - vlan number (for attr->atype == SWLIB_ATTR_GROUP_VLAN)
+ ->value.i (for attr->type == SWITCH_TYPE_INT)
+ ->value.s (for attr->type == SWITCH_TYPE_STRING)
+ - owned by the caller, not stored in the library internally
+ ->value.ports (for attr->type == SWITCH_TYPE_PORT)
+ - must point to an array of at lest val->len * sizeof(struct switch_port)
+
+ When getting string attributes, val->value.s must be freed by the caller
+ When getting port list attributes, an internal static buffer is used,
+ which changes from call to call.
