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. - - */ - -#ifndef __SWLIB_H -#define __SWLIB_H - -enum swlib_attr_group { - SWLIB_ATTR_GROUP_GLOBAL, - SWLIB_ATTR_GROUP_VLAN, - SWLIB_ATTR_GROUP_PORT, -}; - -enum swlib_port_flags { - SWLIB_PORT_FLAG_TAGGED = (1 << 0), -}; - - -struct switch_dev; -struct switch_attr; -struct switch_port; -struct switch_val; - -struct switch_dev { - int id; - const char *name; - const char *dev_name; - int ports; - int vlans; - struct switch_attr *ops; - struct switch_attr *port_ops; - struct switch_attr *vlan_ops; - struct switch_dev *next; - void *priv; -}; - -struct switch_val { - struct switch_attr *attr; - int len; - int err; - int port_vlan; - union { - const char *s; - int i; - struct switch_port *ports; - } value; -}; - -struct switch_attr { - struct switch_dev *dev; - int atype; - int id; - int type; - const char *name; - const char *description; - struct switch_attr *next; -}; - -struct switch_port { - unsigned int id; - unsigned int flags; -}; - -/** - * swlib_connect: connect to the switch through netlink - * @name: name of the ethernet interface, - * - * if name is NULL, it connect and builds a chain of all switches - */ -struct switch_dev *swlib_connect(const char *name); - -/** - * swlib_free: free all dynamically allocated data for the switch connection - * @dev: switch device struct - * - * all members of a switch device chain (generated by swlib_connect(NULL)) - * must be freed individually - */ -void swlib_free(struct switch_dev *dev); - -/** - * swlib_free_all: run swlib_free on all devices in the chain - * @dev: switch device struct - */ -void swlib_free_all(struct switch_dev *dev); - -/** - * swlib_scan: probe the switch driver for available commands/attributes - * @dev: switch device struct - */ -int swlib_scan(struct switch_dev *dev); - -/** - * swlib_lookup_attr: look up a switch attribute - * @dev: switch device struct - * @type: global, port or vlan - * @name: name of the attribute - */ -struct switch_attr *swlib_lookup_attr(struct switch_dev *dev, - enum swlib_attr_group atype, const char *name); - -/** - * swlib_set_attr: set the value for an attribute - * @dev: switch device struct - * @attr: switch attribute struct - * @val: attribute value pointer - * returns 0 on success - */ -int swlib_set_attr(struct switch_dev *dev, struct switch_attr *attr, - struct switch_val *val); - -/** - * swlib_get_attr: get the value for an attribute - * @dev: switch device struct - * @attr: switch attribute struct - * @val: attribute value pointer - * returns 0 on success - * for string attributes, the result string must be freed by the caller - */ -int swlib_get_attr(struct switch_dev *dev, struct switch_attr *attr, - struct switch_val *val); - -#endif |
