-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.
